Onibaku Idler privacy policy

Last updated 11 November 2026. Onibaku Idler is made by Onibaku (admin@onibaku.co.uk).

Where it runs

The game runs on your iPhone or Android phone. There's no Onibaku account and no sign-in. Your progress (heroes, gold, gems, upgrades, settings and what you've bought) is saved on your device only. Deleting the app deletes it.

Play stats (optional)

To make the game better, it sends anonymous play stats to our own analytics server (Umami, run by us). They say what happened, not who you are: which screens you open, runs and floors cleared, upgrades and trinkets picked, which in-app product you tried to buy, when the game stalls for more than a second (how long, and on which screen), the game's build number, and progress numbers such as your best floor and party level. Each one also carries your device's language and screen size.

No name, email, advertising ID or device ID of ours is sent. Your internet address is used to work out your country and city and to group one session's events together; the address itself isn't stored. Stats are never sold, shared or used for advertising, and they aren't linked to you.

Turn them off at any time: tap the cog (or your party's portrait during a run), then Play stats. Nothing is sent while it's off.

Purchases

In-app purchases are made through Apple's App Store or Google Play, so Apple or Google handles the payment under its own privacy policy. We receive only the sales reports they give every developer. The game remembers what you've bought on your device so it can unlock it, and Restore purchases in the Shop asks the store for it again.

Ratings

Now and then, after a good run, the game may ask Apple or Google to show its standard rating prompt. The store decides whether it appears, and your rating goes to the store, not to us.

What it doesn't do

• No account, sign-in or contact details.
• No ads, ad networks, advertising ID or tracking across apps and websites.
• No location (beyond the country and city above), contacts, camera, microphone or photos.
