Trial
Terms of Service
The short version
Trial is a free app for running habit experiments with friends. Be decent to the people in your group, only post photos you have the right to post, and understand that this is a habit tracker rather than a doctor. You own what you write and photograph.
1. Who this agreement is with
These Terms are between you and Elisa Ma, an individual developer in the United States who operates Trial ("we", "us"). By creating an account or using the app you agree to them. If you do not, do not use the app.
2. Who can use Trial
You must be at least 13 years old. If you are under the age of majority where you live, you need a parent or guardian to agree to these Terms on your behalf.
3. Your account
You can sign up with an email address, with Apple, or with nothing at all. If you start without an account, your data lives only on that device's session — if you lose the device or sign out, it is gone, and we cannot recover it for you. Adding an email or an Apple ID later fixes that.
Keep your sign-in details to yourself. You are responsible for what happens under your account.
4. What you post
You keep ownership of everything you post. Your photos, captions and messages are yours.
You give us only the permission needed to actually run the service: to store your content, and to show it to the specific people entitled to see it under the Trial's visibility settings and our Privacy Policy. That permission is limited to operating Trial. It does not let us advertise with your content, sell it, license it to anyone, or use it to train any model. It ends when you delete the content or your account.
5. The app itself is ours
Trial — the app, its name, its design, its code, the experiments in its library, and everything in it that is not content you posted — belongs to us. Using Trial gives you a personal, limited, non-exclusive, non-transferable, revocable licence to use it as published on the App Store. It transfers nothing else to you.
You may not:
- Copy, reproduce, republish, or distribute the app or any part of it.
- Reverse engineer, decompile, or disassemble it, or otherwise try to derive its source code — except to the extent the law says that right cannot be taken away.
- Modify the app or make anything derived from it.
- Build, publish, or help anyone else build a product that copies Trial or reproduces a substantial part of its design, its features, or the way it works.
- Scrape, harvest, or systematically extract data from Trial by any means, automated or otherwise.
- Rent, sell, sublicense, or otherwise sell access to it.
- Remove or obscure any notice of ownership.
None of this stops you describing Trial, writing about it, or telling people what you think of it. It stops you taking it.
Where you got the app from the App Store, Apple's own licence terms for apps apply alongside these, and Apple is not responsible for Trial.
6. Rules for using Trial
Do not use Trial to post or do any of the following:
- Anything sexual involving a minor, or any sexual content posted without the consent of everyone in it.
- Harassment, threats, hate speech, or targeting somebody because of who they are.
- Photographs of other people who have not agreed to be photographed and posted.
- Content that encourages self-harm, disordered eating, or extreme restriction. Trial is deliberately built to avoid this — the experiments we suggest add things rather than take them away — and content pushing the opposite is not welcome here.
- Violence, gore, or anything illegal.
- Spam, scams, or advertising.
- Impersonating somebody else.
- Breaking into, overloading, or automating against the service, including trying to reach data that is not yours or guessing invite codes.
We can remove content and suspend or delete accounts that break these rules.
7. Reporting and moderation
Every check-in and message can be reported from inside the app, and you can block anyone. Reports are reviewed and objectionable content is removed within 24 hours, along with the account responsible where that is warranted.
To report something urgently, email [email protected].
8. Public Trials
If you make a Trial public, people outside your group can follow it, and if you list it they can join it. If you list a Trial, understand that strangers may join and that you are choosing to put the experiment in front of people you do not know.
Photos in a public Trial stay hidden unless the host turns sharing on, and any member can withdraw their own photo regardless of what the host has approved. If you are a host, approving somebody's photo for the public is a decision about another person — treat it that way.
9. Trial is not medical advice
This is a habit tracker, not a health service. Nothing in the app — including the suggested experiments, the daily questions, the charts, and any pattern insights — is medical, psychological, or nutritional advice, and none of it comes from a licensed professional.
Talk to a doctor before starting anything that could affect your health, especially if you are pregnant, have a medical condition, are taking medication, or have a history of disordered eating. If you are struggling with your mental health, please reach out to a professional or a crisis line rather than to a habit app. You take part in any experiment at your own risk.
10. Availability, price and warranties
Trial is free to use. Some features may become paid later — the pattern insights are the likely candidate — and if that happens we will say so in the app before it takes effect.
If the app told you something stays free for your account, it stays free for that account for as long as Trial is running. If you joined before the public launch and we said your pattern insights are free, that holds for the life of the app, whatever we later charge anyone else. You do not have to do anything to keep it, and turning the feature off and back on does not lose it.
We are not promising the app will run for ever, because nobody can. If Trial shuts down, everything in this section ends with it — and we would tell you before that happened.
We may change, suspend, or stop parts of the app, and we will try not to do that in ways that lose your data without warning.
The app is provided as is, without warranties of any kind, express or implied, including merchantability, fitness for a particular purpose, and non-infringement. We do not promise the app will be uninterrupted, error-free, or that it will help you build any particular habit.
11. Limitation of liability
To the fullest extent the law allows, we are not liable for indirect, incidental, special, consequential, or punitive damages, or for lost data, lost profits, or lost opportunities arising from your use of Trial. Where liability cannot be excluded, it is limited to one hundred US dollars ($100).
Some jurisdictions do not allow these exclusions, in which case they apply only as far as the law permits, and nothing here limits liability for fraud, or for death or personal injury caused by negligence.
12. Ending it
You can delete your account at any time from Settings, which deletes your data as described in the Privacy Policy. We can suspend or end your access if you break these Terms. Sections 4, 5, 9, 10, 11 and 13 survive the end of this agreement.
13. Governing law
These Terms are governed by the laws of the State of California, United States, without regard to its conflict-of-law rules. Any dispute goes to the state or federal courts located in California, and you and we both consent to that.
Nothing here removes a right you have under the consumer-protection law of the place you live, if that law says it cannot be removed.
14. Changes to these Terms
If these Terms change in a way that matters, the version at the top changes and the app asks you to read and agree again before you carry on. We do not carry an old agreement over to a new document.
