Terms of Service

Effective 5 August 2026 · Last updated 5 August 2026 · Applies to the AvoLens mobile app (app.avolens.mobile) and this website.

Read this first — AvoLens is not a medical device AvoLens is a tracking tool. Nutrition estimates, medication levels and AI coach replies are informational and can be wrong. They are not medical advice, not a diagnosis, and no substitute for your doctor, pharmacist or dietitian. Never start, stop, delay or change the dose of any medication based on this app. If you think you may have a medical emergency, call your local emergency number.

1. Accepting these terms

These Terms of Service (“Terms”) are an agreement between you and VOLTGENIX LLC (trading as Ash Build) (“AvoLens”, “we”, “us”), the provider of the AvoLens mobile app and this website (together, the “Service”). By downloading, installing or using the Service, you accept these Terms and our Privacy Policy. If you do not agree, do not use the Service.

2. Who can use AvoLens

You must be at least 13 years old — or 16 where local law sets a higher age of digital consent — and legally able to enter into this agreement. If you are under 18, you should have a parent or guardian review these Terms with you.

AvoLens is not designed for, and should not be used to manage, an eating disorder. If calorie tracking is harmful to you, please stop using the Service and speak to a professional.

3. Your licence to use the app

We grant you a personal, non-exclusive, non-transferable, revocable licence to use the Service on devices you own or control, for your own non-commercial use. You may not sell, sublicense, rent or redistribute it.

4. Accounts

An account is optional — AvoLens works fully offline without one. If you create one, keep your credentials secure and give accurate information. You are responsible for activity under your account. Tell us promptly if you suspect unauthorised access.

5. AvoLens Pro

AvoLens Pro includes unlimited AI scans, barcode scanning, nutrition-label scanning, voice logging, the AI Coach, unlimited manual entry, food database search, weight and BMI tracking, trends, GLP-1 tracking, water tracking, widgets, and health data sync.

We may change what AvoLens Pro includes; if a change materially reduces what you already pay for, we will tell you before it takes effect.

6. Subscriptions, billing and cancellation

AvoLens Pro is an auto-renewing subscription, offered on monthly and annual terms.
Payment is charged to your Google Play or Apple account at confirmation of purchase. We never receive or store your payment card details.
It renews automatically unless you cancel at least 24 hours before the end of the current period. Your account is charged for renewal within 24 hours of the period ending.
Cancel in your store’s subscription settings — Google Play → Subscriptions, or Apple ID → Subscriptions. Deleting the app does not cancel a subscription.
Prices are shown in your local currency before you buy, and may change. Price increases take effect only at the next renewal after notice, in line with store rules.
If a free trial is offered, any unused portion is forfeited when you buy a subscription.
Restore purchases is available on the paywall if you reinstall or switch devices, as long as you use the same store account.

7. Refunds

Purchases are handled by Google Play and Apple, and their refund policies apply. Request a refund through the store you bought from — we cannot issue refunds for store purchases directly. Nothing here limits statutory rights you may have, including EU/UK consumer withdrawal rights.

8. AI features and accuracy

Photo scanning, label scanning, voice logging and the AI Coach use automated systems that produce estimates. They can be wrong — sometimes substantially — about portion size, ingredients, cooking method, hidden fats and sugars, or the contents of a packaged product.

Every AI estimate is editable before you log it. Review it.
Do not rely on AvoLens where an incorrect nutrition value could harm you — for example carbohydrate counting for insulin dosing, allergen avoidance, or a medically prescribed diet. Verify with the product label or your clinician.
Food database results come from Open Food Facts, a community-maintained database we do not control or verify.
AI features need an internet connection and may be unavailable, rate-limited, or changed at any time.

9. Health, nutrition and medication disclaimer

AvoLens is not a medical device and does not provide medical advice. It does not diagnose, treat, cure or prevent any condition, and it does not prescribe or recommend dosing.

Calorie and macro targets are calculated with a standard population formula (Mifflin-St Jeor) and are general estimates, not a prescription for your body.
The GLP-1 feature is a log. Dose ladders shown are the manufacturers’ published values, presented so you can select what you were already prescribed. They are not a recommendation and are not personalised to you.
Medication levels, adherence figures and reminders are informational conveniences. Do not treat a missed or mistimed reminder as clinical guidance.
Consult a qualified professional before starting any diet, exercise or medication regimen, and especially if you are pregnant or breastfeeding, under 18, or managing diabetes, kidney disease, an eating disorder or any other medical condition.

Never start, stop, delay or change a dose based on this app.

10. Your content

Your food log, photos, weights, measurements and notes remain yours. You grant us only the limited licence needed to operate the Service for you: to store and sync your data when you are signed in, and to transmit what you submit to our AI provider so it can produce the result you asked for. We do not use your content to train AI models, and we do not use it for advertising. You can export it to CSV or delete it at any time.

You are responsible for having the right to upload anything you upload.

11. Acceptable use

Do not: reverse engineer, decompile or tamper with the Service; access it by automated means or resell access; interfere with or overload our infrastructure or our providers’; circumvent usage limits, entitlement checks or payment; upload unlawful content or content depicting other people without their consent; or use the Service to give medical advice to others.

12. Third-party services

The Service relies on Supabase, Google (Gemini API), RevenueCat, Open Food Facts, Google Play, Apple, Health Connect and Apple Health. Your use of those services is governed by their own terms, and we are not responsible for their availability, accuracy or conduct. See the Privacy Policy for what each one receives.

13. Intellectual property and trademarks

The Service, its design, code, text and the AvoLens name and logo are owned by us or our licensors and are protected by intellectual property law. These Terms grant you no rights in them beyond the licence in section 3.

AvoLens is an independent application. It is not affiliated with, endorsed by, or sponsored by any pharmaceutical manufacturer, health organisation, or the maker of any other app. Any medication names used are the generic (non-proprietary) names of active substances, used descriptively to let you record what you were prescribed. All third-party trademarks remain the property of their owners.

14. Availability and changes

We aim to keep the Service running but do not guarantee uninterrupted availability. We may modify, suspend or discontinue features, and we may set or change usage limits on AI features. If we discontinue the Service entirely we will give reasonable notice so you can export your data.

15. Disclaimer of warranties

To the fullest extent permitted by law, the Service is provided “as is” and “as available”, without warranties of any kind, express or implied, including merchantability, fitness for a particular purpose, non-infringement, and any warranty as to the accuracy or reliability of nutrition estimates, calorie targets, health data or AI output. Some jurisdictions do not allow certain exclusions, so parts of this section may not apply to you.

16. Limitation of liability

To the fullest extent permitted by law, we are not liable for indirect, incidental, special, consequential or punitive damages, or for loss of data, profits, or health outcomes arising from your use of or reliance on the Service. Our total aggregate liability for any claim is limited to the greater of the amount you paid us in the twelve months before the claim, or USD 50.

Nothing in these Terms limits liability that cannot lawfully be limited, including for death or personal injury caused by negligence, or for fraud.

17. Indemnity

You agree to indemnify us against claims, losses and reasonable costs arising from your misuse of the Service, your violation of these Terms, or your infringement of someone else’s rights.

18. Termination

You may stop using the Service at any time and delete your account from Settings → Data & privacy → Delete account or via the web deletion request. We may suspend or terminate access if you materially breach these Terms, with notice where practical. Sections 9, 10, 13, 15, 16, 17 and 19 survive termination.

19. Governing law and disputes

These Terms are governed by the laws of Texas, United States, without regard to conflict-of-law rules, and the courts of Texas, United States have jurisdiction. If you are a consumer, you keep the protections and the right to bring proceedings under the mandatory law of your country of residence — nothing here takes that away.

Please contact us first at avolens@voltgenix-llc.com: most issues are resolved faster by email than by filing.

20. Changes to these terms, and other details

We may update these Terms. The date at the top changes, and for material changes we will notify you in the app before they take effect. Continued use afterwards means you accept them.
If any provision is held unenforceable, the rest stays in force.
Our failure to enforce a provision is not a waiver of it.
You may not assign these Terms; we may assign them in a merger or sale of the app, with notice.
These Terms and the Privacy Policy are the entire agreement between us about the Service.
Apple App Store users: these Terms are between you and us, not Apple. Apple is not responsible for the Service or for support, and Apple and its subsidiaries are third-party beneficiaries entitled to enforce these Terms against you.
