Privacy policy

Updated: 2026-05-24

Short version: no user accounts. Your preferences (active cards, location, favourites) are stored in your browser only. No third-party tracking cookies. No data sold.

1. What we collect

• City-level approximate location (via Cloudflare Pages headers) to suggest nearby stations. Never stored server-side.
• Anonymous navigation events (page views, decision-card clicks, partner clicks) — no cookies, no fingerprint, random per-tab session ID. Helps us improve the product.
• Price alerts: if you subscribe, your email or Telegram ID is stored in our Cloudflare D1 database until you unsubscribe.

2. What stays in your browser

• Driving profile (vehicle, consumption, value of time) — localStorage gasapp.prefs.v1
• Saved location — gasapp.lastpos.v1
• Favourite stations — gasapp.favs.v1
• Language choice — gasapp.lang

Wipe your data: clear this site's local storage in your browser.

3. Affiliate links

Some links (credit cards, insurance comparators, tire shops) earn us a commission. They visibly carry the "Affiliate link" badge and the rel="sponsored nofollow" attribute. We share no personal data with these partners — it's their own cookie that loads on their site when you land there.

4. Your rights (Loi 25 — Quebec)

You have rights of access, correction and deletion for any personal data we hold about you (essentially: alert subscriptions). Email [email protected] — 30-day reply window.

5. Retention

Anonymous events kept for up to 24 months. Alert subscriptions: until you unsubscribe.

6. Subprocessors

• Cloudflare (hosting, edge functions, D1 database) — Canada/US
• Resend (email alert delivery) — US
• Telegram Bot API (Telegram alerts) — international
