Terms of Use

Stack Track · Last updated November 13, 2026

These terms are an agreement between you and Wogi Inc. ("we", "us") for your use of the Stack Track app and service. By creating an account or using the app you agree to them. If you do not agree, do not use the app. Our Privacy Policy and Consumer Health Data Privacy Policy explain how we handle your information.

1. Who can use Stack Track

You must be at least 18 years old, or the age of majority where you live if that is higher. The app is for your own personal, non-commercial use. You are responsible for the information you enter being accurate, because the app uses it to tailor what it shows you.

Stack Track is offered through the App Store and Google Play in the countries where we have made it available there. It is provided in English.

You confirm that you are not located in a country that is subject to a US government embargo or that the US government has designated as a "terrorist supporting" country, and that you are not on any US government list of prohibited or restricted parties.

2. What the app does and does not do

• Tracking. The app records the items, amounts and schedules you choose and reminds you if you ask it to.
• General information for supplements in our catalog. Suggested amounts, timing, cycles and notes about combinations are general information for healthy adults. They are not prescriptions, dosing instructions or personalised medical advice. A suggestion is never an instruction: the decision about what to take is yours.
• How the information is produced. Our catalog was compiled from published sources with the help of artificial intelligence models. What the app shows you is then produced by fixed rules applied to that catalog and the details you entered. It is not written for you by an AI in real time, and no doctor, pharmacist or dietitian reviews your account. The catalog may contain errors, may be out of date, and does not cover every supplement, condition, medication or combination.
• No warning does not mean safe. The app checks only what is in its catalog against the details you gave it. If it shows no warning, that does not mean a supplement, an amount or a combination is safe for you.
• No diagnosis or treatment. The app is not a medical device and does not diagnose, treat, cure or prevent any disease or medical condition. Using it does not create a doctor–patient relationship with us. Statements about supplements in the app have not been evaluated by the US Food and Drug Administration or by any other medicines or food authority.
• Rules differ by country. Which supplements may be sold, in what amounts, and whether a prescription is needed differ from country to country. The app's reference values are primarily United States values; where European values differ, the app shows them. Something in our catalog may be a medicine, need a prescription or be restricted where you live, and the app does not tell you that. Check the rules of your country, and ask a pharmacist or doctor there.
• When the app says "talk to your doctor". For some combinations of health details and supplements the app shows no suggestion. That is not a medical assessment of you; it means general information is not appropriate.
• Reminders. Reminders depend on your device and its settings and may be late or not appear. Do not rely on the app for anything where a missed or repeated dose could harm you.
• No products. We do not sell supplements, and naming a supplement or product in the app is not a recommendation to buy or take it.

3. Items you add yourself

You can add items that are not in our catalog, including prescription medication, peptides, hormones and other substances. For these, the app only records what you enter. It gives no guidance about them, does not check whether they are safe, legal or appropriate for you, and does not check them against your other items. Being able to choose a kind of item, such as "medication", "peptide" or "hormone", does not mean we approve of it or consider it safe. Follow the instructions of whoever prescribed it. Do not rely on the app to tell you that something you added is safe.

For some substances the app may show reference information about their regulatory status in the United States, such as whether a substance is approved by the Food and Drug Administration or available only on prescription, with its sources. That information is general and may be incomplete or out of date. It describes the United States only; the status of a substance in your country may be different. It is not medical or legal advice, and it does not tell you whether a substance is safe or lawful for you.

4. Scanning labels

Barcodes are looked up in public label databases, and label photos are read by an artificial intelligence model run by another company. Both can be wrong or incomplete. Always check the result against the product in your hand before saving it. Photograph only the product label.

5. Your account

You sign in with Apple or Google. Keep your device and those accounts secure; you are responsible for activity under your account. You can delete your account at any time in Settings; this page explains how, including if you no longer have the app.

6. Free and Premium plans

• Free plan. The free plan has limits, including the number of items you can track. Premium removes those limits and adds further features described in the app at the time you subscribe.
• Automatic renewal. Premium is a subscription. The purchase screen shows the plan, its price and its length before you buy. Payment is charged to your Apple or Google Play account when you confirm the purchase, and the subscription then renews automatically for the same period at the same price until you cancel.
• How to cancel. You can cancel at any time in your Apple account's subscription settings or in Google Play, under Payments & subscriptions. Cancel at least 24 hours before the end of the current period to avoid being charged for the next one. Cancellation takes effect at the end of the period you have paid for, and you keep Premium until then.
• Deleting is not cancelling. Deleting the app or your Stack Track account does not cancel a subscription.
• Refunds. Purchases are processed by Apple or Google, not by us, and refunds are handled by them under their own policies (Apple, Google Play). We do not refund part of a period you have already paid for, unless the law requires it.
• Right to withdraw in Europe. If you live in the European Economic Area or the United Kingdom, the law gives you 14 days to withdraw from an online purchase, with exceptions for digital content you have asked to receive straight away. You buy the subscription from Apple or Google, so you use this right with them, under their terms (Apple, Google Play). Nothing in these terms takes it away.
• Trials and offers. If we offer a free trial or an introductory price, the purchase screen will say how long it lasts and what you will be charged afterwards. Unless you cancel before it ends, the subscription continues at that price.
• Price changes. We may change the price for future periods. You will be told in advance, as Apple's or Google's rules and the law require, and you can cancel before the new price applies.
• When a subscription ends, the free plan's limits apply again.

7. Acceptable use

Do not misuse the service: no attempts to break or overload it, to access other people's data, to copy our catalog or content in bulk, to reverse engineer the app except where the law allows, or to use it to give medical advice to others.

8. Our content and your content

The app, its catalog and its content belong to us or our licensors. We give you a personal, non-exclusive, non-transferable licence, which we can withdraw if you break these terms, to use the app on devices you own or control, as these terms and the rules of the store you got it from allow. What you enter remains yours; you allow us to store and process it to provide the service, as described in the Privacy Policy.

If you choose to take part in research, we may also use de-identified information to study, in aggregate, how supplement use relates to wellbeing, and we own the resulting aggregated findings. The Privacy Policy explains how this works and how to opt out. Findings are observations about groups, not advice for you.

9. Disclaimers

The app and all information in it are provided "as is" and "as available", without warranties of any kind, express or implied, including warranties of merchantability, fitness for a particular purpose, accuracy, completeness and non-infringement, to the fullest extent the law allows.

We do not promise that the service will be uninterrupted or error-free, that the information in it is correct or complete, or that reminders will always be delivered. You are responsible for your own decisions about what to take.

If you are a consumer, the law of your country may give you guarantees about digital services that a contract cannot take away, for example that the service is provided with reasonable care and matches its description. This section does not exclude them.

10. Limits on our liability

To the fullest extent the law allows, we are not liable for indirect, incidental, special, consequential or punitive damages, or for loss of data, arising from your use of the app or reliance on information in it. Our total liability for all claims is limited to the greater of the amount you paid for Stack Track in the 12 months before the claim arose and USD 50.

Nothing in these terms excludes or limits:

• liability for death or personal injury caused by our negligence;
• liability for fraud or intentional misconduct;
• any right, guarantee or remedy that the consumer law of the country where you live gives you and that cannot be excluded or limited by contract;
• any other liability that cannot be excluded or limited by law.

Some countries and states do not allow some of the limits in sections 9 and 10, so they may not apply to you. If you live in New Jersey, sections 9 and 10 apply only as far as New Jersey law allows and do not limit your rights under New Jersey's consumer protection and product liability laws.

11. Ending use

You can stop using the app and delete your account at any time. We may suspend or end access if you seriously or repeatedly break these terms, or if we must do so by law. We may change or discontinue features; if we end the service we will give reasonable notice where we can. Sections 8 to 10 and 17 continue to apply after your use ends.

12. Changes to these terms

We may change these terms when the app, its features or prices, the law or the stores' rules change. If we change them in a way that matters, the app will show you the new terms before the change takes effect and ask you to accept them. If you do not agree, stop using the app and cancel any subscription.

13. Apple

If you downloaded the app from the Apple App Store:

• These terms are between you and us, not Apple. We, not Apple, are solely responsible for the app and its content.
• Your licence is to use the app on Apple-branded products that you own or control, as allowed by the Usage Rules in the Apple Media Services Terms and Conditions. Other accounts linked to yours through Family Sharing or volume purchasing may also use it.
• Apple has no obligation to provide maintenance or support for the app.
• If the app fails to conform to a warranty that the law does not allow us to disclaim, you may notify Apple, and Apple will refund the purchase price, if any. To the fullest extent the law allows, Apple has no other warranty obligation for the app.
• We, not Apple, are responsible for addressing claims by you or anyone else relating to the app or your use of it, including product liability claims, claims that the app fails to meet a legal or regulatory requirement, and claims under consumer protection, privacy or similar laws.
• If someone claims that the app, or your use of it, infringes their intellectual property rights, we, not Apple, are responsible for investigating, defending, settling and discharging that claim.
• Apple and its subsidiaries are third-party beneficiaries of these terms. Once you accept them, Apple has the right to enforce them against you.

Your use of the app must also comply with the App Store's own terms.

14. Google Play

If you downloaded the app from Google Play: these terms are between you and us, not Google. We, not Google, are responsible for the app, its content and its support, and Google has no responsibility or liability under these terms. Your use of the app must also comply with the Google Play Terms of Service; if these terms conflict with the rights Google Play's terms give you for apps you download there, those rights apply.

15. Other companies' terms

When you use the app you must also follow the terms of other companies that apply to that use, such as your agreement with your mobile network or internet provider.

16. Support

We provide support by email at info@wogi.io. Questions, complaints and claims about the app should be sent there or to the address in section 19.

17. Law and disputes

If you have a concern, please contact us first; most can be settled quickly by email.

These terms are governed by the laws of the State of Delaware, USA. Disputes will be handled by the state or federal courts located in Delaware, unless the law where you live gives you the right to bring a claim there. Either of us may instead use the small claims court where you live.

If you are a consumer who lives outside the United States, the choice of Delaware law does not take away the protection of the rules of your own country that cannot be set aside by contract. If you live in the European Economic Area, the United Kingdom or Switzerland, you may bring a claim in the courts of the country where you live, and we will bring any claim against you only there.

18. General

These terms are the whole agreement between you and us about the app. If a court finds part of them unenforceable, the rest still applies. If we do not enforce a term, we have not given it up. You may not transfer your rights under these terms; we may transfer ours to a company that takes over the service. Except as section 13 says about Apple, nobody else has rights under these terms.
