Terms of Use

Effective October 28, 2026

By using Daystrand, you accept these terms. They are written plainly; take two minutes to read them.

1. The service

Daystrand is a personal journal that helps you follow your pills, mood, cycle, reading, films, gym and nutrition, and talk with the people close to you. It is run by Jules Martineau, in Quebec (Canada).

2. Not medical advice

Daystrand is an organizing tool. It makes no diagnosis, does not replace a doctor, pharmacist or other health professional, and must not be used on its own to make a medical decision. Cycle predictions, nutrition targets and reminders can be wrong or late (phone off, notifications blocked, outage). Always follow your health professional's directions. In an emergency, call your country's emergency number (911 in Canada and the United States, 112 in Europe).

3. AI meal analysis

With Daystrand+, the app can estimate a meal from a photo, a voice note or text. This is an estimate made by an artificial intelligence: the foods, portions and nutrition values can be wrong. Always check the result before relying on it, and never use it to manage an allergy, an intolerance or a prescribed diet. Analysis is limited to 25 per day and may be unavailable at times.

4. Your account and devices

You must be at least 14, or have the consent of a parent or guardian. Keep your password and backup code to yourself: anyone who knows them can access your journal. Each phone gets its own key; you can sign out other devices in Settings, Backup. You can delete your account and data at any time in Settings.

When the service reaches capacity, we may temporarily refuse new installs. Existing installs keep working.

5. What you post

You keep ownership of what you write and send. You only allow us to store it and deliver it to the people you choose, for as long as needed to run the service. You are responsible for what you send.

6. Zero tolerance

You may not use Daystrand to send or share:

• harassment, threats, bullying or hate speech;
• non-consensual sexual content, or any content sexualizing minors;
• graphic violence, illegal content or encouragement of self-harm;
• spam, scams, or someone else's content without the right to share it.

You may not try to access someone else's account, work around the service's limits or disrupt how it runs.

You can report a message or a person and block them right in the app. We review reports within 24 hours, remove content that breaks these rules and may suspend or delete the account involved.

7. Third-party content and services

Information and images about films, series, books, foods, exercises, songs and GIFs come from outside services and belong to their owners. This product uses the TMDB API but is not endorsed or certified by TMDB. Music previews are provided by Apple and Deezer. If you link your Spotify account, Spotify's terms also apply to that feature.

8. Availability

We do our best for Daystrand to work well, but the service is provided as is, with no guarantee that it will always be available or free of errors. Keep backup on so you lose nothing.

9. Liability

To the extent permitted by law, the operator is not liable for indirect damages resulting from use of the app, including a missed reminder, a wrong nutrition estimate or lost data. Nothing in these terms limits the rights you have under Quebec's Consumer Protection Act.

10. Purchases

In the iPhone app, the Daystrand+ subscription unlocks the gym, nutrition and AI meal analysis, books, movies and shows, music, photos, videos and voice messages in chats, and the widget. Pills, reminders, the journal, mood, cycle, backup, the lock and text messages stay free, and so does exporting your journal.

• The subscription is sold by Apple on the App Store, under its terms. The price, length and free trial are shown before purchase.
• It renews automatically at the end of each period, at the same price, unless you cancel at least 24 hours before. The amount is charged to your Apple account.
• You can manage or cancel it anytime in your Apple account settings. Access stays on until the end of the period already paid.
• If you have a free trial, the subscription starts automatically when the trial ends unless you cancel before.
• Refunds are handled by Apple.

People who used Daystrand before the subscription existed keep access to everything, for free.

11. Ending

You can stop using Daystrand and delete your data whenever you want. We may suspend an account that breaks these terms. If we ever had to close the service, we would tell you in the app at least 30 days ahead so you can export your journal.

12. Governing law

These terms are governed by the laws of Quebec and Canada. If the app was downloaded from the App Store, Apple's standard license agreement also applies.

13. Changes and contact

If these terms change in an important way, we will tell you in the app. To reach us: support form.
