Cookie policy
What this site and the game keep in your browser, why, and how to remove it. Last updated 31 August 2026.
1. Cookies and what stands in for them
Strictly speaking this site uses no cookies: nothing is written to document.cookie
and nothing is sent back to a server with each request. What is used instead is
localStorage — the browser's own storage, which stays on your device and is never
transmitted anywhere by itself.
The law treats both the same way, so both are listed here.
2. What the site stores
One entry, and only after you answer the banner.
| Name | Kind | Category | What it is for | Kept for |
|---|---|---|---|---|
| tnk.consent | localStorage | Site | Remembers your answer to the cookie banner so it is not shown on every page | Until you clear it |
There is nothing else: no analytics, no advertising pixels, no embedded players, no social buttons that watch you. That is why the banner has nothing to unlock — declining changes nothing, because nothing non-essential is loaded either way.
3. What the game stores when you play
The game runs in the browser and keeps a few things on your device. Without the first three it cannot work at all: a session that is not remembered means signing in on every reload.
| Name | Kind | Category | What it is for | Kept for |
|---|---|---|---|---|
| bt.session | localStorage | Essential | The sign-in token: without it every reload would ask for the password again | 30 days |
| bt.email | localStorage | Essential | The address of the last sign-in, so the form is not typed twice | Until you sign out |
| bt.client.id | localStorage | Essential | A random identifier for a guest with no account, so a battle survives a reload | Until cleared |
| bt.settings | localStorage | Preference | Sound, image quality, aiming aids — your settings | Until cleared |
| bt.chassis · bt-hangar-tank · bt.preset · bt.botskill · bt-ranked-role | localStorage | Preference | The last machine, loadout, bot difficulty and ranked role you chose | Until cleared |
| bt-campaign-v1 · bt-levels-v1 · bt-daily-v1 · bt-survival-v1 · bt-onboarding-v1 | localStorage | Preference | Progress of the parts that are played offline: campaign, editor maps, the shot of the day | Until cleared |
| bt-playtest-v1 | localStorage | Local measurements | Turn timings collected during play. It never leaves the browser — nothing is sent to us | Until cleared |
The last row deserves a note: the game measures how long turns take, to see whether three action points are enough. It stays in your browser — the measurement is read by whoever runs the playtest, on their own machine, and is not sent to us.
4. Third parties
No third-party scripts run on this site. During a purchase you are taken to the page of our payment processor, InfraServEdge, which sets its own cookies for its own security — its policy applies there, and the card details never come back to us.
5. How to remove all of it
Clearing the site data for this domain in your browser removes everything listed above. In Chrome and Edge: Settings → Privacy → Site settings → View permissions and data stored across sites. In Firefox: Settings → Privacy & Security → Cookies and Site Data. In Safari: Settings → Privacy → Manage Website Data.
Removing the game's entries signs you out and resets local settings; the account and everything on the server stay untouched.
