Membership Agreement

This agreement is made between a user who creates an optional account in Yaqin (the “Member”) and TooStack (Maslak, Sarıyer, Istanbul; help@toostack.com). Matters not covered here are governed by the Terms of Use.

Membership lets you back up your custom dhikrs, favorites, dhikr sessions and settings to the cloud and restore them on your other devices. Membership is optional; all core features of Yaqin work without an account.

An account is created with a one-time code sent to your email address, Sign in with Apple, or Sign in with Google.

• You must be at least 13 years old to create an account. If you are under 18, you need the consent of a parent or guardian.
• You must use an email address or sign-in account that belongs to you and that you can access.
• Your account is personal and may not be shared or transferred.

You are responsible for not sharing sign-in codes and for keeping your email or sign-in account secure. If you suspect unauthorized use, notify help@toostack.com right away.

Backed-up data is accessible only with your account; database-level access rules prevent other users from seeing it. The provider and region where data is stored will be stated in the Privacy Policy before the feature launches.

You agree to use your account only to back up your own data, lawfully and in line with this agreement, and not to overload the service with automated tools or try to bypass its security.

We provide the backup service with reasonable care but do not guarantee it will be uninterrupted. Don't treat the cloud backup as your only copy; we recommend also using “Export data” for important data. If we discontinue the service, we will give at least 30 days' notice so you can export your data.

You can delete your account at any time in the app (Settings › Account › Delete account) or by writing to help@toostack.com from your registered email address. When your account is deleted, your account information and all cloud backups are removed from our servers immediately and from technical backups within 30 days at most. Data on your device stays there unless you delete it separately. Details: Data & Account Deletion.

If you seriously breach this agreement or the Terms of Use, we may suspend or close your account after notifying you. Even then, we will give you a reasonable period to export your data, except in urgent cases such as unlawful activity.

We will notify you of significant changes to this agreement in the app or by email before they take effect. If you don't accept them, you can delete your account.

This agreement is governed by the laws of the Republic of Türkiye. Istanbul (Çağlayan) Courts and Enforcement Offices have jurisdiction; your rights as a consumer to apply to Consumer Arbitration Committees and Consumer Courts remain unaffected.
