Checkpoint: Megacity
This policy explains what information Checkpoint: Megacity ("the game") handles. The game is made by Checkpoint Development ("we", "us").
What the game stores on your device
- Your save game, a daily backup of it, your settings and your progress.
- If you use the optional "city voices" feature (see below): the voice model you download, your choice of model, and any AI-written lines you report.
All of this stays on your device. It is never uploaded to us or to anyone else. You can remove it at any time: delete the voice models in Profile › Settings › Conversations, start a new game in Profile › Settings, or uninstall the game (or clear its data in your phone's settings) to remove everything.
What we collect
Nothing. The game does not ask for your name, email address, contacts, location, photos, files, camera or microphone, and it does not use any advertising or analytics services. We have no servers that the game sends information to.
City voices (optional on-device AI)
Version 1.2 and later include an optional feature, "city voices", that lets the game's characters answer in their own words using a small AI language model. It is off unless you turn it on in Profile › Settings › Conversations.
- The model runs entirely on your device. What you type and what characters reply is processed on your phone only and is never sent to us or to anyone else.
- The model is not included with the game. If you choose to download one, the game fetches it once from Hugging Face (huggingface.co). Like any download, that request reveals your device's IP address to Hugging Face, under Hugging Face's privacy policy. No game data or personal information is sent with it.
- If you report a line the AI wrote, it is hidden and kept on your device. It is only sent to us if you choose to email your reports, using your own email app.
Buying the game
The game is sold through Google Play. Google handles the purchase and payment under Google's Privacy Policy. We never receive your payment details. Google gives developers standard sales reports (for example, which country a purchase was made in), and we don't use them to identify anyone. Once you've bought the game, there is nothing else to buy: no in-app purchases, subscriptions or paid extras, and the city voices models are free.
If you email us
If you write to us, we receive your email address and whatever you choose to send, and we use it only to reply to you. We don't add you to any mailing list or share your message. Ask us and we'll delete the conversation.
Children
The game is not directed at children under 13. It deals with mature themes (corruption, surveillance and violence in a fictional city), and it does not knowingly collect information from anyone, of any age.
Security
Because the game keeps everything on your device and sends nothing to us, your information is as safe as your device. Keeping your phone locked and up to date protects your save too.
Changes to this policy
If a future version adds a feature that handles personal information, we will update this page before that version is released and change the effective date above.
