Privacy policy
Lantern Legends · Updated October 12, 2026
This policy describes what the Lantern Legends Android game stores. It is the same policy linked from the Google sign-in screen.
What the game is
Lantern Legends is a card game. You build a party, walk a campaign, and fight by drawing three lines. You can play without a Google account.
Google account data
If you tap Sign in with Google, Google shares your email address and a Google account identifier with this game. We use those only to attach your existing game save to that Google account, so the same progress can be opened again later.
We do not read your Gmail, contacts, files, photos, calendar, or any other Google product. We do not send you email. We do not sell Google account data, and we do not share it with anyone except Google Firebase, which stores the save.
A guest game uses an anonymous Firebase sign-in and does not receive your email.
Game data we store
Progress is stored in Google Firebase under your account id. That includes your commander name, party, fighters, items, campaign position, and similar game state. The game does not ask for your location, contacts, photos, or microphone.
Usage events
The release build records anonymous usage events through Firebase Analytics, such as that the app opened, so we can tell whether the game is working. Analytics does not collect the advertising ID.
Ads
A short full-screen ad can play after a stage ends. A one-time purchase in the shop removes those ads on that account. The shop also offers an optional free gift: you choose to watch a short video and receive in-game items. There are no ads during a battle. Ads are served by Google AdMob, which may use your device's advertising ID, IP address, and device information to show and measure ads, as described in Google's advertising policy.
Where the law requires it (for example in the EEA and UK), the game asks for your consent through Google's consent form before loading any ad. You can change that choice any time in Settings, under Ad privacy choices. You can reset or delete the advertising ID in your Android settings.
Purchases
The shop sells optional Gem packs, a one-time starter bundle, and a one-time remove-ads purchase through Google Play. Google handles the payment; we never see your card or billing details. When you buy, the game sends the Google Play purchase token to our server, which checks it with Google and adds the purchase to your save. We keep a record of the product, the order id, and the time so a purchase is granted exactly once. Every unit and item can also be earned by playing.
Sign out
Sign out in Settings starts a new guest game on that phone. The save linked to Google stays on the server until you sign in with that Google account again.
How long data is kept
Game progress stays until you delete the game. Purchase records (product, order id, and time) are kept after deletion so a refund or a second grant of the same order can be handled. Anonymous analytics follows Firebase's retention. Ad data is handled by Google AdMob under Google's policy.
Children
Lantern Legends is not directed at children under 13. It is not in Google Play's Designed for Families program. It has optional Google sign-in and optional purchases.
Delete your game
Settings includes Delete this game. That erases the party, progress, ladder entry, and the Firebase account, then starts a new guest game on that phone. The same steps are written at lantern-band.web.app/delete. You can also email netspens@gmail.com from the Google address on the account and ask for the save to be deleted.
