1. This agreement
By installing or using Lido ("the app") you accept these terms. If you do not accept them, uninstall the app; there is no account to close and nothing to cancel. The terms are between you and the app's developer ("we", "us"), reachable at [email protected].
2. Your licence
We grant you a personal, worldwide, royalty-free, non-exclusive and non-transferable licence to install and use the app on devices you own or control, for as long as you like. You do not owe us anything for it.
You may not:
- sell, rent, sublicense or redistribute the app as your own;
- remove or alter the app's attributions, or repackage a modified build under the Lido name or mark;
- use the app to break the law, or attempt to interfere with other apps or with the device's security through it.
3. Price
Lido is free. There are no in-app purchases, no subscription, no paid tier and no advertising. No feature is withheld pending payment. If a future version ever offered something paid, the free functionality described here would keep working.
4. Not medical advice
Lido is a personal tracking tool. It is not a medical device, and it does not provide medical advice, diagnosis or treatment.
Its goal suggestions are general rules of thumb, not a clinical recommendation. Your appropriate fluid intake depends on your body, your health, your medication, your activity and your climate, and both too little and too much water can be harmful. If you have a kidney, heart or liver condition, are pregnant, are managing a condition that affects fluid balance, or have been given a fluid target by a clinician, follow their guidance rather than the app's. Never delay seeking medical advice because of something Lido showed you.
5. Your data is yours — and your responsibility
Everything you log is stored only on your device, as described in the privacy policy. That has a consequence worth stating plainly: we cannot recover your data for you. There is no server-side copy, no support tool that can look up your history, and no way for us to restore anything. Data can be lost if you delete it in the app, uninstall the app, reset or lose the device, or if the device fails.
If your history matters to you, export a JSON backup from Settings → Export and backup and keep it somewhere you trust. Exported files are yours; we claim no rights over them.
6. Reminders
Reminders are scheduled through Android and are delivered on a best-effort basis. Your device's battery optimisation, doze mode, per-app restrictions, "do not disturb" settings or a manufacturer's power management can delay or suppress them. Lido is not a safety-critical alarm, and you should not rely on it to prompt medication, medically directed fluid intake, or anything else where a missed notification matters.
7. Ownership
The app, its name, its droplet mark, its design and its code remain ours or our licensors'. These terms grant you the licence in section 2 and nothing more. Lido is built on open-source libraries from Android Jetpack, licensed under the Apache License 2.0; those licences continue to apply to those components and are listed in the app under Settings → About Lido.
8. No warranty
The app is provided "as is" and "as available", without warranty of any kind, express or implied, including any implied warranty of merchantability, fitness for a particular purpose, accuracy or non-infringement. We do not warrant that the app will be uninterrupted, error-free, compatible with every device, or that its calculations, reminders or statistics will be free of defects.
9. Limitation of liability
To the fullest extent the law allows, we are not liable for any indirect, incidental, special, consequential or punitive damages, nor for lost data, lost profits, or any health consequence, arising from your use of or inability to use the app. Where liability cannot lawfully be excluded, it is limited to the amount you paid for the app — which is nothing.
Nothing in these terms limits any right you have under mandatory consumer-protection law in your country, and nothing excludes liability for death or personal injury caused by negligence, or for fraud.
10. Availability and changes
We may update the app, change or remove features, or stop distributing it. A copy you have already installed keeps working on your device, offline, for as long as your Android version supports it — there is no server to switch off and no licence check that can fail.
11. Changes to these terms
If these terms change, the updated version will be published here with a new effective date. Continuing to use the app after that date means you accept the revision. If you do not, uninstalling is the remedy.
12. Google Play
When you obtain Lido through Google Play, Google's own terms also apply to that transaction and to the store. Google is not a party to this agreement and has no obligation to provide support for the app. Any refund or store-level issue is handled under Google's policies.
13. Governing law
These terms are governed by the laws applicable at the developer's place of residence, without regard to conflict-of-law rules, and disputes will be brought before the courts of that place. If you are a consumer, this does not deprive you of the protection of the mandatory law of your own country of residence, nor of the right to bring proceedings there where that law gives it to you.
14. The rest
If a provision of these terms is found unenforceable, the remainder stays in force. A failure to enforce a provision is not a waiver of it. These terms, together with the privacy policy, are the whole agreement between us about the app.
