Cookie Policy — Inburger A1

Last updated: 2026-07-11

This Cookie Policy explains what cookies and similar storage technologies Inburger A1 uses, why we use them, and what choices you have. It is a supplement to our Privacy Policy.

What is a cookie?

A "cookie" is a small text file stored on your device when you visit a website. Modern browsers and mobile apps also use related storage mechanisms like localStorage, sessionStorage, and IndexedDB. We refer to all of these collectively as "cookies" in this policy.

What we use

Inburger A1 uses the minimum storage required to function. We do not use third-party advertising or marketing cookies. We do not have a cookie banner because we do not set non-essential cookies without your explicit consent.

Strictly necessary (always active, no consent required under GDPR Article 6(1)(f))

Name	Type	Purpose	Duration
current_profile	localStorage	Remember which profile is active (multi-profile users)	Until you delete app data
<profile>:lezen_state_v1	localStorage	Per-profile reading mastery progress	Until reset
<profile>:stats_v2	localStorage	Per-profile session history	Until reset
<profile>:aanvul_srs_v1	localStorage	Per-profile aanvulzin progress	Until reset
<profile>:exam_date	localStorage	Your saved target exam date	Until reset
inburger_subscription_v1	localStorage	Cached subscription tier (validated server-side)	Until subscription expires or reset
migration_v3_profiles	localStorage	Internal one-time data migration flag	Permanent

These cookies are essential to deliver the features you actively use. Without them the app cannot remember your progress between sessions.

Functional (active if you opt in)

None currently.

Analytics / Marketing

None. We do not use Google Analytics, Facebook Pixel, advertising trackers, or any third-party analytics.

Optional crash reporting (if enabled)

If you opt in to anonymous crash reporting (Settings > Privacy):

Name	Type	Purpose	Duration
sentry_session_id	localStorage	Tie a crash report to a session	24h

This is opt-in only and stores anonymous data only.

Cookies set by payment processors

When you make a purchase, you are redirected to Stripe Checkout (web) or interact with Apple App Store / Google Play (mobile). Those services set their own cookies governed by their own policies:

• Stripe Cookie Policy: https://stripe.com/cookies-policy/legal
• Apple Privacy: https://www.apple.com/legal/privacy/
• Google Privacy: https://policies.google.com/privacy

We do not control those cookies. They are not set in our app/site directly.

Cookies set by Anthropic (AI grading)

When you submit an answer for AI grading, the request goes to Anthropic's Claude API. Anthropic may set transient cookies during the API request. We have no control over those.

Your choices

• Clear all our cookies: open the app and go to Settings > Reset profile, OR clear your browser's data for our domain, OR delete the mobile app.
• Disable cookies entirely: configure your browser. The app will not function correctly without localStorage.
• Withdraw analytics consent (if opted in): Settings > Privacy > Analytics.

Updates

We may update this policy. The "Last updated" date reflects the most recent change.
