Terms of Use

Last updated: 26 April 2026

These terms are a contract between you and mondaybrew ApS, a Danish limited liability company (CVR 45217779; "mondaybrew", "we", "us") for use of the Sauerdo iOS app and the Sauerdo Pro subscription. They incorporate Apple's standard end-user licence terms for apps distributed through the App Store.

1. The licence

We grant you a personal, non-transferable licence to install and use Sauerdo on any iOS device you own or control, limited by the terms Apple publishes for App Store apps in the Apple Media Services Terms. You may not sell, sublicence, reverse engineer, or redistribute the app.

2. Subscriptions — Sauerdo Pro

Sauerdo Pro is an auto-renewable subscription. You can choose:

Auto-renewal

Prices and local taxes

Prices may vary by region and may include local taxes. Prices shown in the app are pulled live from Apple's StoreKit and represent the price applicable to your App Store account. We may change prices; existing subscribers are notified in line with Apple's rules.

What Sauerdo Pro unlocks

Restore

You can restore a previous purchase on any device signed into the same Apple ID via the paywall's Restore purchases button.

3. Your content

4. Acceptable use

Don't use Sauerdo to break the law, to store content that is illegal in your jurisdiction, or to try to disrupt the app or the App Store (reverse engineering, injecting code, spoofing receipts, etc.).

5. No warranty

The app is provided "as is". We do our best to keep it working, but we can't guarantee it's error-free, that fermentation predictions are correct for your kitchen, or that iCloud mirroring will always succeed on a given day. Use the in-app journal as a reference, not a food-safety authority.

6. Limitation of liability

To the fullest extent permitted by law, our total liability for any claim arising from your use of Sauerdo is limited to the amount you paid us for the app or subscription in the 12 months before the claim.

7. Termination

You can stop using the app any time and delete it from your device. We can terminate your licence if you breach these terms. Subscription billing stops in line with Apple's subscription rules; we do not independently charge you.

8. Apple's role

Apple is not a party to this agreement, but as required by Apple: Apple is the third-party beneficiary of these terms and may enforce them against you. Apple has no obligation to provide maintenance or support for the app. Apple's App Store terms govern the actual purchase and delivery.

9. Changes to these terms

We may update these terms. Material changes will be posted at sauerdo.vercel.app/terms with an updated "Last updated" date. Continuing to use Sauerdo after a change means you accept the updated terms.

10. Governing law

These terms are governed by Danish law, without reference to its conflict of laws rules. Courts in Copenhagen, Denmark have non-exclusive jurisdiction, subject to any mandatory consumer-protection rights in your own country of residence.
