Privacy Policy
This policy explains how Yaylog Operator (“we” or “us”) handles information in the app “Yaylog” (the “App”) and on this website.
1. Our approach
The App is designed not to send your records off your device. There is no account, and the App contains no ads, analytics or tracking. The App does not use advertising identifiers (such as IDFA).
2. Information the App handles
Records (what you did, tags, dates) and settings
- Stored only on your device. They are not sent to us or anyone else.
- If you use your OS backup (iCloud or Google backup), your records are included in it. Backups are handled under Apple’s or Google’s privacy policy.
- Files you export are saved wherever you choose (Files, cloud storage, email, etc.).
Purchase information (Yaylog Plus)
- Purchases and payments are processed by Apple or Google. We never receive your payment method or card details.
- To check the status of purchases, we use the service of RevenueCat, Inc. (USA). The App sends RevenueCat:
- A random identifier created automatically by the App (not linked to your name or email address)
- Purchase history and receipts (product, purchase date, expiration, etc.)
- Basic information about your device and the App (OS and version, App version, language and region, etc.) and your IP address for communication
- This information is used only to decide whether you can use Plus, to restore purchases and to prevent fraudulent purchases. RevenueCat handles it under the RevenueCat Privacy Policy.
- Even if you don’t use paid features, the identifier and device information above may be sent, for example when you open the purchase screen.
3. Information this website handles
- This website is delivered by Cloudflare, Inc. For delivery and security, Cloudflare may process access logs (IP address, browser type, time of access, etc.).
- This website does not use cookie-based analytics or ads.
4. Information you send us
If you contact us by email, we use your email address and message only to reply and respond to you.
5. Sharing with third parties
Except as described above or as required by law, we do not provide your information to third parties.
6. International transfers
RevenueCat and Cloudflare are US companies, and information may be processed in the United States and other countries.
7. Retention and deletion
- Records and settings: They exist only on your device. They are removed when you delete them in the App or delete the App. We do not hold your records, so there is nothing for us to delete. Please delete any copies left in your OS backup or in files you exported.
- Purchase information: RevenueCat keeps it for as long as needed to check and restore purchases, under the RevenueCat Privacy Policy. To request deletion, contact us (see “Contact” below). Because the identifier is not linked to your name, we will ask for information such as the order ID in the purchase confirmation email from Apple or Google, find the matching data and delete it. After deletion, “Restore purchases” may no longer restore Plus.
- Emails you send us: We delete them once they are no longer needed after we have responded.
- You can ask us to disclose, correct, delete or stop using information about you that we hold. Please contact us (see “Contact” below).
8. Children
The App does not knowingly collect information from children.
9. Changes to this policy
We may change this policy when necessary. Changes take effect when posted on this page. We will announce important changes in the App or on this website.
