Privacy policy
Your drinks stay on your own phone. What we do process is listed below.
In short
Your drinks, your weight and your blood alcohol stay on your own phone. We do not sell data and we do not show ads based on your profile.
What the app stores
The app stores your input locally on your device: profile, drinks and settings. Without an account none of this leaves your phone.
If you create an account to share a night with friends, we store your email address, your display name and what you share in that night. You decide what you share and you can delete your account.
Feedback you send through the app is kept after you delete your account, without your name or account and not linked to you.
Without an account of your own, the app can use an anonymous account to sync your data. When that anonymous account has not been used for 90 days, we delete it together with the data synced to it. What is stored on your phone stays on your phone.
What the website measures
This website uses no cookies and no tracking. We only count visits per page anonymously, without IP address or any other personal data and without following you across sites.
This website counts visits with Cloudflare Web Analytics. It works without cookies and does not follow you across other sites; we only see totals, such as the number of visits and which pages are viewed.
Error reports
If the app freezes or hits an error, it sends the error anonymously: the type of error, the app version and the type of device. No drinks, no BAC, no names and no account. You turn this off in Settings under Privacy.
Anonymous usage counts
We send anonymous usage counts, never your drinks, weight or identity. They are counters: that the app was opened for the first time (and whether through an invite, a friend link or on your own), that a night was started, that an invite was opened or used, and how many days were between your first and second night (0 to 7, 8 to 28 or 29 and more). Each counter carries only the platform (web, Android or iOS) and the app version (major and minor number only).
No name, email address, account, device ID, location, drink, weight or BAC goes with it, and we do not keep an IP address. A counter is not sent right away but after a random wait of up to 6 hours, so no exact time is attached. In our weekly figures we never show a result below 10 counts. We keep the raw counters for at most 90 days.
You turn this off in Settings under Privacy, at Anonymous statistics. Turning it off stops it at once and deletes anything still waiting to be sent.
