Aha!

Cookie Policy

Last updated: 27 May 2026 Effective date: 27 May 2026

This Cookie Policy explains how the Aha website (https://ahabuldum.app and https://ahaweb.sabriekmen.workers.dev) uses cookies and similar browser-based storage technologies. For personal-data processing details related to cookies, please also read our Privacy Notice.


1. What is a Cookie?

A cookie is a small text file that a website places in your browser and can read back on later visits. This Policy also covers browser localStorage and sessionStorage, which store preferences in your browser in a similar way.

2. Cookies We Use

The site uses only strictly necessary cookies and anonymous analytics. We do not use advertising, profiling, or third-party marketing cookies.

Vercel AnalyticsAnonymous analyticsRequest headers / no fingerprintSessionAggregate metrics such as page views, country, and device type. Does not identify individual users and does not set a cookie.

The mobile application (Aha) does not use browser cookies. In-app preferences are kept in secure on-device storage.

3. Legal Basis for Cookies

  • Strictly necessary cookies (NEXT_LOCALE, theme, language, sidebar_state): no consent is required because they are needed to deliver the service you requested, in line with Turkish Law No. 5651 and the Personal Data Protection Authority's 2022 cookie guidance.
  • Anonymous analytics (Vercel Analytics): produces aggregated, non-identifying statistics; not personal data, processed on the basis of legitimate interest.

4. Managing Cookies

You can delete or block cookies in your browser at any time:

  • Chrome: Settings → Privacy and security → Cookies and other site data
  • Firefox: Settings → Privacy & Security → Cookies and Site Data
  • Safari: Preferences → Privacy → Manage Website Data
  • Edge: Settings → Cookies and site permissions

To clear localStorage, use "Clear site data" from the same menus.

If you block cookies, the site still works, but your language and theme preferences will reset on every visit.

5. Third-Party Links

The site may link to Apple App Store, Google Play, GitHub, and similar sites. When you follow such a link, that site's own cookie and privacy policy applies; Aha has no control over those sites' practices.

6. Changes to This Policy

We may update this Policy. Material changes are announced on the website and the effective date at the top is updated. If you have an Aha account, we will notify you by email before a material change takes effect.
