Privacy Policy

Last updated: 11 October 2026

What we collect

An account holds your email address, your display name, the languages you read, and your reading position in each text. If you sign in with Google we receive your email address, name and profile picture from Google. While you are signed in we also record each reading session — when it starts and ends, how many paragraphs you read and how many explanations you ask for — to understand how the site is used; these records are deleted after 90 days.

Why we collect it

To keep your place in a book across devices, to show your library, and to apply the daily limits attached to your plan. We do not sell personal data, and we do not use it for advertising.

Where it is stored

In a Postgres database and object storage hosted in Frankfurt, Germany, inside the European Union.

Who processes it

Paralelo runs on Fly.io (hosting, database and object storage, Frankfurt). Sign-in uses Google, or an email address and a password, of which we keep only a hash. Account emails (address confirmation, password reset) are sent by Resend. Payments are handled by Stripe, through Link. Errors are reported to Sentry. Analytics, only with your consent, is Google Analytics. Each of these sees only what it needs to do its job.

Texts you import

A text you import is stored, with its translation, in the same storage as the rest of your account, in Frankfurt. It is read by our translation and alignment services to build it, and by no one else except the people you share it with. Deleting the text deletes it everywhere, and deleting your account deletes every text you imported. When you confirm your rights to a text, we record when you did and from which address.

How long it is kept

Your account and reading positions are kept for as long as the account exists, and are erased when it is deleted. Records of payments are kept for as long as tax law requires, which in France is ten years. Analytics data expires after 14 months.

Your rights

Under the GDPR you may request a copy of your data, correct it, or have it deleted. Deleting your account removes your profile, your reading positions and your saved list. There is no button for it yet: write to privacy@paralelo.app and it will be done by hand, within a month, and you will be told when it is finished.

Cookies

A session cookie keeps you signed in and a preference cookie remembers your chosen interface language and your reading filters. Those are necessary for the site to work and are always set. Separately, and only if you accept the banner, Google Analytics is loaded and sets its own cookies so we can count visits and see which pages are read; your IP address is anonymised and nothing you read is sent with it. Nothing is loaded before you accept, declining costs you nothing, and you can change your answer at any time from the link in the footer.
