Privacy

Alcohol Journal is provided by Tahsin Kaan Çakır. For privacy questions or data requests, contact kaan@tkaancakir.com.

Your journal stays on your device

Drinking/alcohol-free records, notes, daily plans, optional journey and last-drink dates, and spending assumptions are stored on your device. The app does not upload these journal records to its content server or membership provider. Language, currency, appearance and whether a supporter invitation has been shown are also stored locally. Your operating system's device-backup settings may apply separately.

Backup files you choose

When you choose export, the app creates a JSON file containing journal information and saves it to the location you select through Files. This file is not encrypted. Selecting a cloud location may transfer and retain it under that provider's terms. Import reads the selected file and replaces the current journal after confirmation. Membership sessions, access tokens and pending-payment records are excluded from journal backups.

Supporter membership

Apple and RevenueCat handle purchase and access verification for membership functions. The content service creates a random app user identifier and associates this pseudonymous identifier with RevenueCat. Product, purchase history, subscription status and entitlement information are processed to provide and verify membership. RevenueCat also processes purchase data for its membership-dashboard functions. The membership SDK may also process technical information such as device type and operating system, and purchase-verification data. Journal notes and drinking records are not submitted with this identifier.

Your payment-card details and Apple Account password are not entered into the app's server. Membership sessions and pending-payment information are stored in iOS Keychain. Deleting the app does not cancel an Apple subscription and should not be assumed to remove Keychain or provider records.

Content service and hosting

Content requests include the selected language, requested article and, when needed, the membership session. The server temporarily processes an IP address in memory to limit excessive requests. The website and content service are hosted on Vercel. Vercel may process connection, access and security information to deliver, secure and operate the service. Hosting-log retention depends on the provider's applicable policies and service settings; this page does not promise an unverified fixed retention period.

Advertising, links and contact

The app has no advertising network or separate behavioral-analytics integration. It has no flow that shares journal records for advertising. This website uses no analytics cookies or contact form. External help, Apple or RevenueCat services have their own terms. If you email us, your sender address and information you choose to share are processed to answer your support request. You do not need to send your journal, Apple password or payment-card details.

Retention and your requests

Journal corrections preserve earlier records in history. The current version has no developer account and no dedicated erase-all-data button. Manage local records through your device's app data, and exported files through the locations where you saved them. Check operating-system backups separately.

Membership, support correspondence and service records are retained as needed to operate the relevant service, verify purchase access, provide security and meet applicable obligations. Provider records are also subject to those providers' retention rules. Send access, correction or deletion requests to kaan@tkaancakir.com. We assess requests under applicable obligations, verifying their scope and identity where necessary. We cannot remotely access journal records that are not uploaded to us.

Service providers

Providers including Apple, RevenueCat and Vercel may operate infrastructure in different countries. Processing is subject to their applicable contractual and privacy arrangements. See Apple privacy, RevenueCat privacy and Vercel privacy.
