These Terms of Service apply to all users of the site, including without limitation users who are browsers, vendors, customers, merchants, and/ or contributors of content.

Terms of Service

Effective date: November 3, 2026

These Terms of Service ("Terms") are an agreement between you and C-Tech Inc. ("C-Tech", "we", "us" or "our"), 216 W 6th Street, San Bernardino, CA 92401, USA. They apply to all of our products and services (together, the "Services"), including:

  • the Vital Eye Health online store at vitaleyehealth.com and the devices and accessories sold there (the "Store");

  • the Vital Eye Health app (vital signs display and alerts);

  • the StediGuard app and website stediguard.com (fall detection, SOS, safe zone and activity features);

  • the VerteGuard app and website verteguard.com (posture coaching);

  • the VigilantHer app and website vigilanther.com (personal safety);

  • WatchMyVitals, including watchmyvitals.com and the dashboards we provide to care facilities and other organizations; and

  • any related subscriptions, wearable bands, firmware, websites, notifications, text messages, calls and support.

By visiting our websites, buying from the Store, creating an account, or downloading or using any of our apps, you agree to these Terms. Product specific terms below apply in addition to the general terms when you use that product; if they conflict, the product specific terms control for that product. If you do not agree, do not use the Services.

Each app and website has its own privacy policy, linked in the app, on its website and in its app store listing. Those privacy policies explain how we handle your information and are part of these Terms.

Please read the Important Safety and Health Notice, the Disclaimer of Warranties, the Limitation of Liability and the Dispute Resolution sections carefully. The Dispute Resolution section requires most disputes to be resolved by individual arbitration and waives your right to a jury trial and to take part in a class action, unless you opt out as described there.

Important Safety and Health Notice

Our products are aids. They are not a guarantee of safety, they are not an emergency service, and they are not medical devices.

  • We do not contact police, fire, ambulance or any emergency service for you. No person at C-Tech monitors your alerts, readings, location or recordings. Our apps notify only the people you choose, and WatchMyVitals shows information only to the organization and staff using it. In an emergency, call 911 or your local emergency number.

  • Not medical advice. Our apps and websites do not diagnose, treat, cure, monitor for treatment, or prevent any disease or condition, and have not been cleared or approved by the US Food and Drug Administration. Some devices sold in the Store are made by third party manufacturers and may carry their own regulatory status; that status belongs to the device, not to our apps. Readings, scores, alerts and coaching are for general wellness, information and convenience only. Always follow the advice of a qualified health professional and the instructions that come with each device. Do not change any medication or treatment based on our Services.

  • Things outside our control. The Services depend on your phone, its battery, settings, permissions and operating system; wearable bands and other devices, their batteries and firmware; Bluetooth, GPS and location accuracy; mobile and internet networks; and third party services that deliver notifications, text messages and calls. Operating systems can limit or stop apps running in the background.

  • Alerts and detection can fail. Alerts, readings, location sharing, check ins, fall detection, safe zone alerts, separation alerts, posture feedback, Unusual Movement, the voice code phrase and recordings may be delayed, inaccurate or incomplete, or may not work at all. Detection features can miss real events and can trigger when nothing is wrong. A notification, text message or call may not be delivered, and the people who receive it may not see it, answer it, or act on it.

  • Features may depend on firmware. Some features may not work at the same time, or may need a specific band firmware version. The apps tell you when this applies.

  • We do not guarantee that any Service will prevent an injury, fall, illness, crime or other harm, that help will arrive, or that any alert will be delivered or acted on. You use the Services at your own risk, and you and, where applicable, your caregivers or organization remain responsible for safety and care decisions.

Eligibility, Accounts and Using the Services for Someone Else

You must be at least 18 years old, or the age of majority where you live if that is higher, to create an account or buy from the Store. VigilantHer is for adults 18 and over only. A person under 18 may use other Services only with the involvement and supervision of a parent or legal guardian who accepts these Terms.

You must give accurate information, keep your login details secure, and tell us if you believe your account has been used without your permission. You are responsible for activity under your account.

If you set up or use a Service for another person, for example a parent you care for or a resident of a facility, you confirm that you have that person's consent or the legal authority to act for them, including to collect their readings and location and to share them with others, and you are responsible for that use.

Your Responsibilities

To get the most from the Services, you agree to:

  • keep phones, bands and devices charged, switched on, within range and updated, and wear or use each device as its guide describes;

  • keep the permissions each app asks for turned on, such as location, Bluetooth, notifications and, where a feature needs it, the microphone;

  • test alerts regularly and fix anything the app reports as needing attention;

  • keep your contacts' and caregivers' details accurate, and tell them what alerts they may receive and what you would like them to do; and

  • not rely on any Service as your only means of getting help or as a substitute for professional care or supervision.

Contacts, Caregivers and Your Circle

Several apps let you add people (called contacts, caregivers or your Circle) to receive alerts and, in some features, your location. You confirm that each person you add has agreed to receive alerts about you, including text messages and automated calls where the app sends them. Message and data rates may apply to them. Text messages are sent only about alerts and related account events, never for marketing. A recipient can reply STOP to stop text messages or HELP for help; if they do, they will no longer receive alerts by text.

Contacts, caregivers and Circle members are not our employees or agents and are not trained responders. We are not responsible for whether or how they respond, or for anything they do or fail to do.

Location Sharing and Monitoring Others

Some features share location with people you choose, for example during an SOS, a walk, a journey, a safe zone alert or a separation alert. Location can be imprecise, delayed or unavailable. You are responsible for choosing who sees location, and you must not use any Service to track, monitor or record another person without their consent or legal authority.

Subscriptions

Some apps offer paid subscriptions, sold through the Apple App Store or Google Play. The price and what is included are shown before you buy and may vary by country.

  • Auto renewal. Subscriptions renew automatically at the end of each period at the then current price, and your App Store or Google Play account is charged, unless you cancel at least 24 hours before the end of the current period.

  • Cancelling. Cancel in your App Store or Google Play subscription settings. Deleting an app or your account does not cancel a subscription. After cancelling, paid features stay available until the end of the period you paid for.

  • Refunds. Subscription payments are handled by Apple or Google, and refunds follow their policies.

  • Changes. We may change prices or the features included in a subscription. Price changes apply from your next renewal and follow the app store's notice rules.

Store Purchases

Orders and pricing. All orders are subject to acceptance and availability. We may refuse or cancel an order, including for suspected fraud, resale, or an error in a price or description, and we will refund any amount charged for a cancelled order. Prices, products and descriptions may change without notice. We try to describe and show products accurately, but colors and details may vary.

Payment and taxes. You agree to give current, complete and accurate purchase and billing information and to pay all charges, including applicable taxes and shipping.

Shipping, returns and refunds. Shipping, delivery, returns and refunds for Store purchases are governed by the shipping and refund policies posted on the Store at the time of your order. Title and risk of loss pass to you when we hand the order to the carrier.

Devices and warranties. Devices are covered only by any warranty stated on the product page or in the box, or by the manufacturer's own warranty. To the fullest extent permitted by law, we make no other warranty for devices. Follow each device's instructions, including charging, cleaning, water resistance and battery safety, and keep small parts away from children and pets.

Resale. Products are sold for personal or organizational use, not for resale, unless we agree otherwise in writing.

Bands, Devices and Firmware

Our apps work with specific wearable bands and devices. A band may need to be paired or linked to your account before its features work, and some features need a specific firmware version. We may provide firmware updates and may require them for some features. Battery life depends on the features you use; some features, such as continuous movement monitoring, may require charging the band daily.

Acceptable Use

You agree not to:

  • start false alarms or use alerts to harass, frighten or mislead anyone;

  • add anyone as a contact, caregiver or Circle member who has not agreed;

  • track, monitor or record another person without their consent or legal authority, or use the Services in any way that breaks the law;

  • misuse the text message or calling features, or use them for marketing;

  • interfere with, overload, reverse engineer, scrape, or try to gain unauthorized access to the Services or other users' information;

  • upload or transmit viruses or harmful code; or

  • resell, copy or exploit the Services except as these Terms allow.

We may suspend or limit features, including texts and calls, if we reasonably believe they are being misused.

Third Party Services

The Services rely on third party providers, including Apple, Google (including Firebase and Google Maps), Twilio (text messages and calls), RevenueCat (subscriptions), Shopify (the Store) and device and band manufacturers. Their services are outside our control, may change or fail, and are subject to their own terms. Links to third party websites are provided for convenience only. We are not responsible for third party services, products, websites, networks or devices.

Testing Versions and Changes to the Services

We may offer early versions through TestFlight, Google Play testing tracks or similar programs. Testing versions may contain errors, are provided for evaluation, and must not be relied on for safety. We may add, change, limit or stop any Service or feature at any time.

Content You Provide and Feedback

You keep ownership of the information and content you provide, such as readings, notes, places and recordings. You give us permission to host, store, process and transmit it only as needed to provide and improve the Services and as described in the applicable privacy policy. If you send us feedback, comments or ideas, we may use them without obligation to you.

Our Intellectual Property and Your License

The Services, including the apps, websites, designs, text, graphics, voice clips, logos and software, belong to C-Tech or its licensors and are protected by law. We grant you a personal, limited, non exclusive, non transferable, revocable license to use our apps on devices you own or control and to use our websites, in line with these Terms and the rules of the app store you downloaded an app from. Vital Eye Health, WatchMyVitals, StediGuard, VerteGuard and VigilantHer are our trademarks; you may not use them without our written permission.

Product Specific Terms

Vital Eye Health App

  • The app displays readings from compatible third party devices, such as blood pressure monitors, pulse oximeters and thermometers, and can send alerts to people you choose. Readings come from the device and may be affected by how it is used. Always follow the device's instructions, and confirm any reading of concern with a health professional.

  • In facility modes (such as Nursing Home or Senior Community), alerts may be shown on a phone or dashboard at the facility instead of being sent to family. The facility is responsible for watching for and responding to alerts.

  • Fall, posture, safe zone, separation and activity features have the same limits described in the Important Safety and Health Notice.

StediGuard

  • Fall detection analyzes movement from your band and can miss falls or alert when no fall happened. It is not a medical fall detection system or a monitoring service.

  • SOS, safe zone, wearer separated and activity alerts, caregiver notifications, and any text messages or calls depend on your phone, band, permissions, networks and caregivers, and on your plan.

  • A countdown or check gives the wearer a chance to cancel before caregivers are alerted; if no one is near the phone, it may expire without anyone responding.

VerteGuard

  • VerteGuard offers general posture awareness and coaching, including vibration and voice reminders. It is not a treatment for back pain, scoliosis or any other condition.

  • Stop using it and talk to a health professional if you feel pain, discomfort or skin irritation, or if you have a medical condition affecting your spine, joints or movement.

VigilantHer

  • VigilantHer is a personal safety aid for adults. SOS, Circle alerts, Walk With Me, smart journeys, HerMoment check ins, Unusual Movement, the voice code phrase and evidence recording all have the limits described in the Important Safety and Health Notice. With current band firmware, the band button may not be detected while Unusual Movement keeps a live connection to the band; Hold SOS on the phone remains available.

  • Recording laws. Some places, including California, require the consent of everyone being recorded. You are solely responsible for deciding whether to turn on recording and for complying with the recording and privacy laws that apply to you and to the people you record. We do not guarantee that any recording will be captured, uploaded, kept, or accepted as evidence.

  • Recording storage is limited per account, currently 500 MB. When recordings exceed the limit, the oldest finished recordings may be deleted automatically to make room. Recordings from the last 24 hours and from an active SOS are not deleted this way. Download anything you want to keep.

  • To prevent misuse and excessive messages, we may limit how often texts and calls are sent, for example a set number of alert rounds per hour. App notifications are not limited this way.

WatchMyVitals for Facilities and Organizations

  • If you use WatchMyVitals or a facility mode on behalf of a care facility, senior community or other organization ("Organization"), you confirm you are authorized to accept these Terms for the Organization, and "you" includes the Organization.

  • The Organization is responsible for its authorized users and their login details; for obtaining any consents and authorizations needed from residents, patients and their representatives; for staffing, supervision, clinical judgment, care decisions and response to alerts; and for complying with the laws that apply to it, including health privacy laws.

  • WatchMyVitals displays information sent from residents' phones and devices. It may be delayed, incomplete or unavailable, for example when a phone is out of Wi Fi range, switched off or out of battery, and it does not replace routine checks, nurse call systems or clinical monitoring equipment.

  • If the Organization is subject to HIPAA, it must contact us to put a business associate agreement in place before using the Services with protected health information. Any separate written agreement signed by C-Tech and the Organization, including pricing and service terms, controls over these Terms where they conflict.

Disclaimer of Warranties

TO THE FULLEST EXTENT PERMITTED BY LAW, THE SERVICES, INCLUDING ALL APPS, WEBSITES, DASHBOARDS, FIRMWARE AND STORE PRODUCTS, ARE PROVIDED "AS IS" AND "AS AVAILABLE", WITH ALL FAULTS AND WITHOUT WARRANTIES OF ANY KIND, WHETHER EXPRESS, IMPLIED OR STATUTORY, INCLUDING ANY WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, TITLE, NON INFRINGEMENT, ACCURACY, AND ANY WARRANTIES ARISING FROM COURSE OF DEALING OR USAGE, EXCEPT FOR ANY WRITTEN DEVICE WARRANTY DESCRIBED IN THE STORE PURCHASES SECTION. WE DO NOT WARRANT THAT THE SERVICES WILL BE UNINTERRUPTED, TIMELY, SECURE OR ERROR FREE, THAT READINGS, ALERTS, LOCATION, DETECTION OR RECORDINGS WILL BE ACCURATE, DELIVERED OR AVAILABLE, OR THAT THE SERVICES WILL PREVENT ANY INJURY, ILLNESS, LOSS OR HARM. SOME JURISDICTIONS DO NOT ALLOW THE EXCLUSION OF IMPLIED WARRANTIES, SO SOME OF THESE EXCLUSIONS MAY NOT APPLY TO YOU.

Limitation of Liability

TO THE FULLEST EXTENT PERMITTED BY LAW, C-TECH AND ITS DIRECTORS, OFFICERS, EMPLOYEES, AGENTS, CONTRACTORS, LICENSORS AND SERVICE PROVIDERS WILL NOT BE LIABLE FOR ANY INDIRECT, INCIDENTAL, SPECIAL, CONSEQUENTIAL, EXEMPLARY OR PUNITIVE DAMAGES, OR FOR ANY LOSS OF DATA, RECORDINGS, PROFITS, REVENUE OR GOODWILL, ARISING OUT OF OR RELATING TO THE SERVICES OR THESE TERMS, INCLUDING ANY FAILURE, DELAY OR INACCURACY OF ANY READING, ALERT, NOTIFICATION, TEXT MESSAGE, CALL, LOCATION, DETECTION, CHECK IN, COACHING OR RECORDING, ANY ACT OR OMISSION OF A CONTACT, CAREGIVER, CIRCLE MEMBER, ORGANIZATION OR OTHER THIRD PARTY, OR ANY FAILURE OF A PHONE, BAND, DEVICE, NETWORK OR THIRD PARTY SERVICE, WHETHER BASED ON CONTRACT, TORT (INCLUDING NEGLIGENCE), STRICT LIABILITY OR ANY OTHER THEORY, EVEN IF WE HAVE BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES.

TO THE FULLEST EXTENT PERMITTED BY LAW, OUR TOTAL LIABILITY FOR ALL CLAIMS ARISING OUT OF OR RELATING TO THE SERVICES OR THESE TERMS WILL NOT EXCEED THE GREATER OF (A) THE AMOUNT YOU PAID US FOR THE SERVICE OR PRODUCT GIVING RISE TO THE CLAIM IN THE 12 MONTHS BEFORE THE EVENT GIVING RISE TO THE CLAIM, OR (B) ONE HUNDRED US DOLLARS (US$100).

These limitations are an essential part of the bargain between you and us and apply even if a remedy fails of its essential purpose. They do not limit liability that cannot be limited by law, such as liability for fraud, gross negligence or willful misconduct where applicable law does not allow it to be limited.

Indemnification

To the extent permitted by law, you agree to defend, indemnify and hold harmless C-Tech and its directors, officers, employees and agents from any claims, losses, damages, liabilities, costs and expenses, including reasonable attorneys' fees, arising from your misuse of the Services, your breach of these Terms, your violation of any law (including recording, privacy and health privacy laws), or your violation of the rights of another person, including anyone you add as a contact, caregiver or Circle member, monitor, or record.

Dispute Resolution and Arbitration

Informal resolution first. Before starting arbitration or a court case, you and we agree to try to resolve any dispute informally for at least 30 days, starting when one side sends written notice describing the dispute. Send notices to us at the contact details below.

Binding individual arbitration. Except as stated below, any dispute, claim or controversy arising out of or relating to the Services or these Terms will be resolved by binding individual arbitration administered by the American Arbitration Association ("AAA") under its Consumer Arbitration Rules (or its Commercial Arbitration Rules for an Organization). The arbitrator decides all issues, except that a court decides questions about whether this section is enforceable, the class action waiver, and the mass filing provisions. Hearings may be held by video or phone, or in San Bernardino County, California, or the county where you live. Fees are paid as the applicable AAA rules provide. The Federal Arbitration Act governs this section.

Exceptions. Either side may bring an individual claim in small claims court if it qualifies, and either side may seek an injunction in court to protect intellectual property.

Class action and jury trial waiver. YOU AND WE EACH AGREE THAT CLAIMS MAY BE BROUGHT ONLY IN AN INDIVIDUAL CAPACITY, AND NOT AS A PLAINTIFF OR CLASS MEMBER IN ANY CLASS, COLLECTIVE, CONSOLIDATED OR REPRESENTATIVE PROCEEDING. YOU AND WE EACH WAIVE THE RIGHT TO A JURY TRIAL. If this waiver is found unenforceable for any claim, that claim must be decided in court, not in arbitration.

Mass filings. If 25 or more similar demands are filed by or with the help of the same law firm or group, the demands will be administered in batches under the AAA's mass arbitration procedures, and the time to respond is extended accordingly.

Opting out. You can opt out of this arbitration agreement by emailing us at the address below within 30 days after you first accept these Terms, with your name, the email on your account or order, and a statement that you opt out of arbitration. Opting out does not affect any other part of these Terms.

Governing Law and Venue

These Terms are governed by the laws of the State of California, USA, without regard to its conflict of laws rules, except that the Federal Arbitration Act governs the arbitration section. For any matter not subject to arbitration, you and we agree to the exclusive jurisdiction of the state and federal courts located in San Bernardino County, California.

Termination

You may stop using the Services and delete your account at any time, using the delete option in the app or by contacting us. We may suspend or end your access if you break these Terms, if required by law, or if we stop offering a Service, with notice where reasonable. Sections that by their nature should continue after termination will continue, including the Important Safety and Health Notice, Disclaimer of Warranties, Limitation of Liability, Indemnification and Dispute Resolution sections.

Apple App Store Terms

If you downloaded an app from the Apple App Store, the following also applies. These Terms are between you and C-Tech only, not Apple, and C-Tech, not Apple, is solely responsible for the app and its content. Your license to use the app is limited to Apple branded devices you own or control, as permitted by the App Store Terms of Service. Apple has no obligation to provide maintenance or support for the app. If the app fails to conform to any applicable warranty, you may notify Apple, and Apple will refund the purchase price, if any; to the maximum extent permitted by law, Apple has no other warranty obligation for the app. C-Tech, not Apple, is responsible for addressing any claims relating to the app, including product liability claims, claims that the app fails to conform to legal or regulatory requirements, and claims under consumer protection, privacy or similar laws. C-Tech, not Apple, is responsible for investigating, defending, settling and discharging any claim that the app infringes a third party's intellectual property rights. You confirm that you are not located in a country subject to a US Government embargo or designated as a "terrorist supporting" country, and that you are not on any US Government list of prohibited or restricted parties. Apple and its subsidiaries are third party beneficiaries of these Terms and may enforce them against you.

Google Play Terms

If you downloaded an app from Google Play, your use is also subject to the Google Play Terms of Service. Google is not responsible for the app or its content.

Changes to These Terms

We may update these Terms from time to time. We will post the new version with a new effective date and, for material changes, notify you in the app, on the website or by email before they take effect. If you continue to use the Services after changes take effect, you accept the updated Terms. Changes to the Dispute Resolution section do not apply to disputes we already knew about before the change.

General

These Terms, together with the applicable privacy policies, Store policies and any separate written agreement with an Organization, are the entire agreement between you and us about the Services. If any part is found unenforceable, the rest stays in effect. Our failure to enforce a provision is not a waiver. You may not transfer these Terms without our consent; we may transfer them as part of a merger, acquisition or sale of assets. We are not liable for delays or failures caused by events beyond our reasonable control, including network, power, carrier or third party outages, natural disasters, and acts of government. Headings are for convenience only.
