Cookie Policy
BackPix stores a few things in your browser. Some it cannot work without. The rest is stored only with your permission, which we ask for on your first visit, except in the United States, where analytics and ad measurement are on from the start and you can turn either off at any time. Session replays run only if you say yes, wherever you are. If your browser sends a Global Privacy Control signal, nothing is shared with Meta. You can change your choice from "Your privacy choices" at the bottom of the front page or in Settings → Cookie choices in the app; one answer covers both.
Always on — needed for the app to work
| What | Set by | Purpose | Lasts |
|---|---|---|---|
Sign-in session (IndexedDB firebaseLocalStorageDb) | Google Firebase | Keeps you signed in | Until you sign out |
backpix.consent.v1 | BackPix | Remembers your cookie choices | 6 months |
backpix.device.v1 | BackPix | A random id used only to stop free credits being claimed repeatedly | Until you clear site data |
backpix.attribution.v1 | BackPix | The link that brought you here (campaign name), kept on this device | Until you clear site data |
Camera and hint preferences (backpix.*) | BackPix | Remembers settings you chose, and whether to open the app rather than this site's front page | Until you clear site data |
reCAPTCHA (_GRECAPTCHA), if enabled | Confirms requests come from a real browser, against abuse | 6 months |
Analytics — only if you allow it (in the US, until you turn it off)
| What | Set by | Purpose | Lasts |
|---|---|---|---|
ph_*_posthog | PostHog (EU) | Recognises your visits so we can see how the app is used; anonymised session replays with your photos and typing hidden, only once you have said yes | 1 year |
With analytics off, PostHog runs in memory only and nothing is stored on your device. Once you are signed in, basic usage is linked to your account's random id, never to your name or email (see the Privacy Policy).
Marketing — only if you allow it (in the US, until you turn it off)
| What | Set by | Purpose | Lasts |
|---|---|---|---|
_fbp, _fbc | Meta | Lets Meta tell us whether an ad led to a visit, a sign-up or a purchase | 90 days |
With this on, Meta also receives, from our server, the sign-up and any purchase, with your email address and account id hashed so they cannot be read. Without it, nothing about you is sent to Meta.
In the iPhone app
The app uses no cookies. It keeps your sign-in and settings in its own storage, and asks before any analytics or ad measurement, wherever you are; nothing optional runs until you answer.
To measure our ads, the app includes Meta's SDK. It reports installs, sign-ups and purchases to Meta only if you allow marketing in the app's privacy choices and then tap "Allow" when your iPhone asks whether BackPix may track you; with either answer no, nothing about you is sent to Meta. Apple's own install measurement (SKAdNetwork) reports campaign totals without identifying you, and works without your permission.
Changing your mind
Use "Your privacy choices" at the bottom of the front page, or Settings → Cookie choices in the web app (Privacy choices on iPhone, where Settings → Privacy → Tracking also turns tracking off). You can also clear site data in your browser settings, which removes everything above and signs you out.
