This Privacy Policy explains how Briefshelf ("Briefshelf", "we", "us" or "our") collects, uses, and protects your personal data when you use our website at briefshelf.com and our mobile application (together, the "Service"). It also describes the rights you have over your data. By using the Service you agree to the practices described here.
Briefshelf provides short-form book summaries you can read or listen to, along with curated learning paths. The data controller responsible for your personal data is Eduard Mateu Molins. If you have any question about this policy or your data, contact us at privacy@briefshelf.com.
We only collect the data we need to run the Service. Specifically:
| Category | What it includes | When we collect it |
|---|---|---|
| Account data | Email address, display name, and a securely hashed password (we never store your password in plain text). | When you create an account with email and password. |
| Sign-in provider data | When you sign in with Google or Apple, we receive a unique identifier, your email address, and (for Google) your name and profile picture. Apple provides your name only on your first sign-in, and may relay a private, anonymised email address. | When you choose "Continue with Google" or "Continue with Apple". |
| Usage & content data | Your library, reading and listening progress, saved summaries, learning-path progress, and reading streaks. | As you use the app, to sync your progress across devices. |
| Device & technical data | A device identifier used to associate a session with your device, plus standard technical information such as IP address and general log data. | Automatically, when you use the Service. |
| Website analytics | Aggregated usage statistics collected via Google Analytics on our website (e.g. pages visited, approximate location, device type). | When you browse briefshelf.com. |
We do not sell your personal data, and we do not use it for third-party advertising.
If you are in the European Economic Area or the UK, we rely on the following legal bases:
We share data only with service providers who help us operate the Service, and only to the extent needed. These include:
These providers act as data processors on our behalf and are bound to protect your data. We may also disclose data where required by law, or to protect our rights, users, or the public.
Some of our providers may process data outside your country, including outside the EEA. Where that happens, we rely on appropriate safeguards such as the European Commission's Standard Contractual Clauses.
We keep your personal data for as long as your account is active. If you delete your account, we delete or anonymise your personal data within a reasonable period, except where we must retain certain information to comply with legal obligations or resolve disputes.
Depending on where you live, you have the right to:
To exercise any of these rights, email us at privacy@briefshelf.com. You also have the right to lodge a complaint with your local data protection authority.
You can request deletion of your account and associated personal data at any time by contacting privacy@briefshelf.com.
We use industry-standard measures to protect your data, including encrypted connections (HTTPS), hashed passwords, and secure storage of authentication tokens on your device. No method of transmission or storage is completely secure, but we work to protect your data against unauthorised access, loss, or misuse.
The Service is not directed to children under 13 (or the minimum age required in your country), and we do not knowingly collect their data. If you believe a child has provided us with personal data, contact us and we will delete it.
We may update this Privacy Policy from time to time. When we do, we will revise the "Last updated" date above and, where appropriate, notify you within the Service. We encourage you to review this page periodically.
