Privacy Policy

Last updated November 13, 2026

Better Sourdough (“the app”) and bettersourdough.app (“the website”) are made by Gyorgy Pesti (“we”, “us”). This policy explains what happens to your data when you use them.

The short version:

  • There is no account. We never ask for your name or email address.
  • Your doughs, bake plans and bakes stay on your device.
  • We collect anonymous usage statistics to understand how the app is used and to fix errors. They are not linked to you.
  • We never sell your data, never use it for advertising and never track you across other apps or websites.

What stays on your device

The amounts you mix, your starter and salt settings, your kitchen and fridge temperatures, your bake plans and the bakes you start, with every step you log, are stored only on your device. They are never sent to us. Removing the app removes them.

Anonymous usage statistics

To learn which parts of the app are used and to find errors, the app and the website send usage events to PostHog, an analytics service whose servers we use in the European Union. The events include:

  • which screens are opened and which buttons are tapped;
  • bake events, such as a bake started or a step logged, with details of the plan (for example counter or fridge proofing) and a random number that identifies the bake;
  • error reports when something goes wrong in the app;
  • the type of device, its operating system, the app version and your language;
  • an approximate location (country or city) that PostHog derives from your IP address.

The events carry a random identifier created on your device (on the website: kept in your browser’s storage), so that events from the same device can be counted together. This identifier is not linked to your name, email address, Apple Account or any other information about you, and we do not combine it with other data. Events travel through our own server at api.bettersourdough.app, which passes them on to PostHog. We keep usage statistics only as long as they help us improve the app.

Purchases

Subscriptions are bought and paid for through the App Store. Apple processes the payment; we never see your payment details or your Apple Account. To check whether your subscription is active, the app uses RevenueCat, which receives a random identifier for the app and the purchase information Apple provides (which subscription, when it was bought and when it renews). Restoring a purchase also goes through your Apple Account.

Reminders and the Lock Screen

If you allow notifications, the app schedules reminders for the next step of your bake on your device itself. The bake in progress is shown on your Lock Screen the same way. Nothing is sent from a server, and you can turn notifications off at any time in your device’s Settings.

What we don’t do

  • We don’t send emails, newsletters or marketing messages.
  • We don’t use the advertising identifier or track you across apps and websites.
  • We don’t sell or share your data with advertisers or data brokers.

Legal basis

Where the EU or UK General Data Protection Regulation applies, we process usage statistics on the basis of our legitimate interest in understanding how the app is used and keeping it working, and purchase information to provide the subscription you bought.

Your rights

You can ask us for access to, correction of or deletion of personal data, object to its processing, or complain to your data protection authority. Because usage statistics are not linked to you, we usually cannot find the events that belong to you; write to us and we will help as far as we can.

Children

The app is a general baking tool and is not directed at children. We do not knowingly collect personal data from children.

Changes

If this policy changes, we will update it on this page and change the date at the top.
