Privacy
Short version: Many Doors collects nothing about you. It only counts, anonymously, how the game is played, and you can turn that off.
Effective date:
What we collect
No personal data. The app has no account or login, no advertising and no tracking, and it sends no personal data to us or to anyone else.
Anonymous usage statistics
To learn which buildings are too hard and whether the game works well, the app sends us anonymous, aggregate usage counts, for example "building 3 started", "building 3 lit", "the unlock offer was shown" or "a tip was bought", with the app version and the day. That is all. The counts contain no name, no account, no device or advertising identifier and no personal data, and they are not linked to you.
Each launch gets a random session number that lives only in the app's memory; it is never saved on your iPhone and never stored on our server. Our server (on Cloudflare) does not store your IP address. It keeps only a scrambled form of the session number, made with a random key that changes every day, for at most two days to count how many sessions there were; then only daily totals remain and the key is deleted. The counts are never used for tracking, advertising or profiling, never combined with data from others, and never sold or shared.
You can turn this off at any time in the app: Settings (the sliders button on the map) → Anonymous usage statistics. When it is off, nothing is counted or sent and anything still waiting on your iPhone is deleted.
iCloud
If iCloud is on, your progress (which buildings you lit and whether Full Building is unlocked) is copied to your own iCloud key-value storage so it survives a reinstall or a new iPhone. Apple stores it under your Apple ID; we have no access to it.
Game Center
If you use Game Center, your scores and achievements are sent to Apple Game Center under your Game Center profile. Apple's privacy policy applies.
Purchases
Tips and Full Building are in-app purchases processed by Apple. We never see your name, Apple ID or payment details; Apple only tells the app whether a purchase went through.
If you write to us (for example with Write to us in Settings, which opens your own mail app with only the app name and version in the subject), we use your address and message only to reply, and we don't share them.
This website
This site sets no cookies and runs no analytics or third-party scripts. Our hosting provider (Cloudflare) briefly processes technical data such as your IP address to deliver the pages and protect them from abuse.
Children
Many Doors collects no personal data from anyone, including children. The anonymous counts above are the same for everyone and can be turned off in Settings.
Changes
If this policy changes, we'll update this page and the effective date above.
