Privacy Policy

The short version

Berth is a player for a Berth server that you, your family or someone you trust runs. Your books, your library and your listening progress live on that server — not with us. The app has no accounts with us, no ads, no advertising identifier and no tracking.

The only data that reaches us is crash and performance reports, used to fix bugs.

Data that goes to your Berth server

When you connect the app to a server — with a QR code, a pairing code or a login and password — and while you use it, the app sends to that server:

• the device name and platform (for example “iPhone 16” and “ios”), so the server owner can see and disconnect the device;
• the login and password, if you sign in with them — once, to get sign-in tokens; the app does not store the password;
• sign-in tokens issued by the server;
• your listening position, playback speed and finished books, so they sync across your devices;
• requests to stream or download the books in that library.

This server is operated by its owner, not by us. We have no access to it or to the data on it. Its owner decides how long the data is kept and who can see it.

Data we receive: crash and performance reports

Release builds of the app send reports to Sentry (Functional Software, Inc.), stored in Sentry's EU region (Germany), when the app crashes or an error occurs, plus timing data on how long screens and requests take. A report contains the error and stack trace, the app version, the operating system version, the device model, timing data and a random installation identifier that is not linked to your name or e-mail.

We use these reports only to find and fix bugs. We do not sell them, do not share them for advertising and do not combine them with data from other sources. Reports are deleted automatically after at most 90 days.

Data that stays on your device

• Camera — used only to scan the QR code of your server. Images are processed on the device and are neither saved nor sent anywhere.
• Motion sensor — used only to notice a shake that extends the sleep timer, on the device.
• Network status — used to choose between your server's home-network and internet addresses.
• Downloaded books, the cached library and settings are stored in the app's own storage on the device.

What we do not do

• No ads and no advertising or analytics SDKs.
• No tracking across apps and websites, no use of the advertising identifier (IDFA / AAID).
• No sale or transfer of personal data to third parties.
• No books or other content from us: the app plays only what is on the server you connect to.

Your choices

• Disconnect: Settings → All servers → “Disconnect from this server” signs the device out and removes that server's library and progress from the phone.
• The owner of the server can disconnect your device and delete your data on the server at any time.
• Deleting the app removes everything it stored on the device, including downloads.
• To delete crash reports from your device sooner than 90 days, write to lialex2016@gmail.com with the device model and the approximate date.

Children

The app is not directed at children under 13 and collects no data that identifies a child. Crash reports contain no names, e-mail addresses or library contents.
