What we collect, and why
| Data | Why |
|---|---|
| Your Telegram id, username and first name | To sign you in and to recognize your account. Your first name is only used as a default display name. |
| Your nickname in the city | It is shown to other players, in the newspaper and in the rankings. If you choose “Private resident”, your nickname is hidden and you appear as “a private resident”. |
| Your wallet address (BDAG, USDT or USDC), only if you link one; a wallet is optional and only needed for real-money transactions | To prove that the wallet is yours (by a signature), to keep one wallet to one account and, later, for badges such as Miner. We never ask for keys or seed phrases and never move funds. |
| Your IP address | Only to limit abuse (rate limiting), in memory. It is not stored in the database and it is not written to our logs for normal requests; it can appear in the server's error logs. |
| The device and approximate location of a sign-in request (for example “Chrome on Android, Bucharest, RO”) | Shown to you in the Telegram bot so that you can check that the sign-in is really yours. |
| Your game data (requests, purchases, balances, notices, the days you open the game) | To run the game. The rules depend on them (for example residency and inactivity), and every game day can be verified from the BlockDAG chain together with these inputs. |
| Feedback and bug reports you send | To fix problems. We keep the message, the page and the time. |
We do not sell your data, we do not show ads based on it, and we do not use tracking cookies. The only cookie is the sign-in session (dc_sid).
What is public
The city is public: buildings, owners' nicknames (unless you are a private resident), public prices, rankings and the Treasury totals. Personal balances are never published. The game's inputs (requests and activity) are published per game day by player id, without names, so that anyone can verify the city.
How long we keep it
- Sign-in sessions: 30 days (unused sign-in links: 1 day).
- Your account and game data: while your account exists. If the city is reset for the test, game data may be archived.
- Error logs on the server: kept by the server's system log, which deletes old entries automatically.
- Automatic daily backups of the database: 14 days.
Deleting your account
Send a request with the “Report a bug / Feedback” button (or write to the DAGCity bot on Telegram) from the account you want deleted. We delete your account, your Telegram data, your wallet link and your sessions within 30 days; your nickname is removed from public pages. Records that the game needs to stay verifiable (for example past turns) keep only your player id, without your name or Telegram data. Automatic backups expire on their own within 14 days.
No real payments
In this phase there are no real payments and we do not collect any payment data. DAG$ is an in-game currency (see the Terms).
