Privacy Policy
Last updated: June 2025
Who is responsible for your data
- Service: BacklogPlanner (backlogplanner.eu)
- Operator: Matteo Batazzi — hello@matteo.design
- This service is operated as a personal project, not a company.
What data we collect and why
- Steam ID and username — to identify your account and display your profile. Collected when you sign in via Steam.
- Steam game library — fetched from the Steam API on each visit to build your backlog list. Not stored permanently.
- Game statuses (completed, endless, retired) — saved so your progress persists across sessions.
- First and last login date — used to understand how the service is used over time.
- Profile visibility setting — whether your profile is public or private.
Legal basis (GDPR)
- Signing in with Steam is voluntary — you consent by using the service.
- Game statuses and profile data are necessary to deliver the service (Art. 6(1)(b)).
- Login timestamps are kept under legitimate interest for basic analytics (Art. 6(1)(f)).
Third parties
- Steam (Valve) — handles authentication and provides your game library. Governed by Steam's own privacy policy.
- Supabase — stores your account data and game statuses. Servers are hosted in the EU (eu-central-1).
- HowLongToBeat / Metacritic — queried by game name only, no personal data is sent.
How long we keep your data
- Your data is kept for as long as you have an account.
- You can delete your account and all associated data at any time from the settings menu.
Cookies
- One session cookie is set when you sign in. It contains your Steam ID and display name, and is used to keep you logged in.
- No advertising or tracking cookies are used.
Your rights
Under GDPR you have the right to:
- Access the data we hold about you.
- Correct inaccurate data.
- Delete your data (use the in-app account deletion, or email us).
