Cookie policy
Last updated: 2026-09-17
Cookies are small files a website stores in your browser. QR Boost uses very few: the technical ones it needs to work and, only if you accept, Google Analytics cookies.
Technical cookies (always on)
They don't need consent because the service can't work without them.
| Cookie | Purpose | Duration |
|---|---|---|
__Host-sid |
Keep you logged in | Browser session, or 400 days if you choose to stay signed in |
otp_email, login_prefs |
Remember your email and preferences while you enter the login code | 15 minutes |
g_oauth |

qb_consent |

We also keep your theme preference (light or dark) in your browser's local storage and, while you create a QR code before logging in, its settings (deleted when you close the tab).
Analytics cookies (only with your consent)
We use Google Analytics 4 on public pages to learn what gets visited.
- If you accept, Google Analytics uses the
_gaand_ga_<ID>cookies (up to 13 months) to tell visits apart. - If you don't accept or don't choose, Google Analytics works without cookies: it sends anonymous pings that don't identify your browser.
- We never enable advertising features, Google signals or ad personalisation.
- Nothing is measured on private pages (My QR codes, My account).
Google acts as a processor. More information: https://policies.google.com/privacy
