Terms of Use
1. Who we are, and what this is about
Hemera (the “App”) is a mobile app that offers one verified historical fact a day, a catalogue of facts sorted by topic, sharing features and a collection of streaks and badges.
The App is published by , , SIRET , whose address is (the “Publisher”). Director of publication: . Contact: .
The App is hosted by Supabase ().
These terms of use (the “Terms”) set the rules for using the App. They form a contract between you and the Publisher.
2. Accepting and changing the Terms
By creating an account or using the App, you accept the Terms. If you do not accept them, do not use the App.
We may change the Terms, for example when the App evolves or the law changes. When a change is significant, we tell you in the App before it takes effect. If you keep using the App after that date, you accept the new Terms; otherwise you can delete your account.
3. Your account
You need an account to use the App. You can create one with your email address (through a sign-in link), with Apple or with Google.
You must be at least 15 years old. If you are under 15, you may only use the App with the permission of a holder of parental authority.
You agree to give accurate information, to create only one account and not to let anyone else use it. You are responsible for the security of your email address and of your Apple or Google account, which you use to sign in. Tell us right away if you think your account was used without your consent.
You can delete your account at any time from the App: Profile, Settings, “Delete my account”.
4. What the App offers
- a personalised fact of the day, chosen from the topics you selected;
- a fact of the day shared by all readers, which you can turn off in Settings;
- a catalogue whose facts can all be read at any time, by topic and by search;
- sharing a fact (text, link and image) with the people of your choice;
- a collection of streaks and badges, which reward your curiosity and never rely on any question, score or answer to give;
The App is free. An optional subscription may be offered: it would remove ads without giving access to extra content. If so, its terms (price, duration, renewal, cancellation, refund) will be shown to you before purchase, and the purchase will be handled by the app store (App Store or Google Play).
We may change, suspend or remove features. We will tell you in the App when a change significantly affects how you use it.
5. Content and accuracy of the facts
Each fact is written and verified before it is published, and gives its source. Despite this care, history is a field where sources may differ and knowledge moves on: a fact may be incomplete or contain a mistake.
Facts are informative and cultural. They are not advice, nor a scientific or academic reference.
If you spot a mistake, write to : we will check it and correct it if it is confirmed.
6. Intellectual property
The App, its name, logo, design, texts and the selection of facts are protected by copyright, trademark law and database rights. All rights are reserved, except those the Terms give you.
We grant you a personal, non-exclusive, non-transferable right to use the App and read its content, for private, non-commercial use, for as long as your account exists.
The App’s sharing feature is made to pass a fact on to other people: you may use it freely. Any other reproduction or public display, systematic extraction of content (for example by robots), resale, or use to train artificial intelligence systems, is forbidden without our prior written consent.
The sources cited belong to their respective owners.
7. Rules of use
You agree not to:
- get around or disrupt the security or operation of the App and its servers;
- access another person’s account or data;
- access the App by automated means (robots, scripts);
- distort your activity (streaks, badges) by technical means;
- use the App unlawfully or to harm others;
- copy, decompile or modify the App, except within the limits the law allows.
You are responsible for how you use the facts you share and for the message that goes with them.
8. Availability
We do our best to keep the App available, without guaranteeing continuous access: maintenance, an incident or your network may interrupt it.
Offline, content already loaded stays readable. Actions taken without a network (facts opened, shares, settings) are sent as soon as possible.
9. Suspension and end of the account
You can stop using the App and delete your account at any time.
We may suspend or delete an account in case of serious or repeated breach of the Terms, after letting you explain, except in an emergency (security, legal obligation).
When an account is deleted, its data is erased as the privacy policy explains.
10. Liability
Nothing in the Terms excludes or limits a liability that cannot be excluded or limited by law, in particular for personal injury, gross negligence or wilful misconduct, nor the rights the law gives you as a consumer, including statutory guarantees.
Subject to that, the Publisher is not liable for indirect damage, for interruptions caused by outside events (network, carrier, app store, force majeure), or for the content of third-party sites cited as sources.
Apple and Google are not parties to the Terms and have no obligation to maintain or support the App. Their own terms govern downloading the App from their store.
11. Personal data
The personal data processed to run the App, and your rights over it, are described in the privacy policy, available from the sign-in screen and from Settings.
12. Governing law and disputes
The Terms are governed by French law. If you are a consumer living in another country of the European Union, you keep the protection given by the mandatory provisions of your country.
For any complaint, write to us first at : we look for an amicable solution.
If you are a consumer, you may use, free of charge, the consumer mediator we are attached to (articles L. 611-1 et seq. of the French Consumer Code): .
Failing an amicable settlement, and if you are a consumer, you may bring the case before the court of the place where you live or of the place where the harmful event occurred, as the law provides.
