Privacy policy

Effective 26 September 2026 · applies to the Fairweek app on Android and iOS.

The short version

• There is no account: no email address, phone number or password is ever asked for.
• Your family's calendar is shared only with the people who joined with your family code.
• The app is free and shows ads from Google AdMob, which uses your device's advertising identifier.
• Anonymous usage statistics show which features help families; they never include names, dates, notes or anything else you type.
• You can delete your data at any time in More → Delete my data.

What the family calendar stores

Fairweek keeps your family's calendar in Google Firebase (Google LLC), on Google Cloud servers in the United States, so that both homes see the same thing. It stores:

• a random, anonymous user identifier created by Firebase Authentication for each phone;
• the name each person chooses to show the family (for example "Alex" or "Mom") and which of the two homes they belong to;
• the names you give the two homes, the kids' first names and, if you add them, their birthdays;
• the regular schedule, the usual handoff time and place, and the holiday rules you choose;
• changes asked for (the nights, the home, any note and reply) and who asked and answered, with times;
• record entries: confirmed handoffs and notes, with who added them and when;
• shared notes about each kid that you choose to write (for example school or clothes sizes);
• the family's six-letter code.

This data is visible only to the members of your family. Record entries, requests and answers cannot be edited or deleted in the app, so that both homes can rely on them. When someone leaves, their name and home are removed and what they added stays with the family. When the last person leaves, or deletes their data, the family's calendar, requests, record and notes are deleted.

Reminders

Handoff reminders are scheduled on your phone. No push notification token is collected, and reminder settings are not uploaded.

Advertising

Fairweek shows banner and occasional full-screen ads through Google AdMob. To serve and measure ads, Google collects your device's advertising identifier (Android Advertising ID; on iOS the identifier for vendors — Fairweek does not ask for permission to track you across other companies' apps), your IP address for approximate location, and how you interact with ads. In the European Economic Area, the UK and Switzerland you are asked for consent before personalised ads are shown, and you can change your choice in More → Ad privacy choices. You can also reset or limit your advertising identifier in your phone's settings. Google's use of this data is described at policies.google.com/technologies/partner-sites.

Usage statistics

Fairweek uses Google Analytics for Firebase (Google LLC) to count how the app is used — for example how many families finish setting up, invite the other home, ask for or answer a change, or export a record. These events carry a random app-instance identifier, your device model, operating system and app version, and an approximate location (country or region) derived from your IP address. They never include names, dates, notes or anything else you type. In the European Economic Area, the UK and Switzerland they are used only as far as you allow in the privacy message. Google keeps this event data for a limited time (at most 14 months).

Crash reports

If the app crashes, Firebase Crashlytics sends a technical report: the error, the device model, the operating system and app versions, and a random installation identifier. Reports are used only to fix bugs.

Children

Fairweek is made for parents and other adults who care for children. It is not directed to children, and we do not knowingly collect data from children. The kids' first names and birthdays are entered by their parents, only to show the family's own calendar.

Your rights

You can see everything in your family's calendar in the app itself, and delete your data with Delete my data (see how deletion works). For any question or request — including access, correction or deletion under the GDPR or other privacy laws — write to [email protected]. The legal bases we rely on are performing the service you ask for (the shared calendar), our legitimate interest in fixing crashes, and your consent where the law requires it for advertising and usage statistics.

Changes

If this policy changes, the new version will be posted here with a new effective date.
