Your privacy, kept simple.
ThinkMantis is built to be private by default. There is no account, no sign-up, and no tracking. Your progress lives on your own device. Here is exactly what that means.
No account, no sign-up.
You can start playing in seconds. We never ask for your email, phone number, or a password, and we don’t create a profile about you. One feature — challenging a friend to a duel — lets you type a name for that friend to see. It is optional, you choose what to put there, and it goes only into the link you send.
Your progress stays on your device.
Everything you build up — your leaves, level, rank, daily streak, settings, and any cosmetics you own — is saved in your browser's local storage, on the device you're playing on. It is not uploaded to us, and it is not shared with anyone. Clearing your browser data, using a different device, or removing ThinkMantis takes this local data with it. Because your progress lives on your device, saving depends on your device having room: if its storage is full, new progress may not save — ThinkMantis shows a notice the first time that happens, so a lost streak is never a surprise.
No ads. No third-party trackers.
ThinkMantis shows no advertising and uses no third-party advertising or analytics trackers. We don't use cookies to follow you around the web.
Feedback you choose to send.
Sending feedback opens Switik’s feedback site in a new tab. It is a separate page from the game: nothing leaves your device until you submit the form there, and what you type goes to Switik. We pass along which game, mode and page you came from, plus the score and challenge on screen, so the note has context. Nothing that identifies you travels with it — no name, no email, no id. The game itself still collects nothing, and you can close the tab without sending anything at all.
The Weekly Boss leaderboard.
The Weekly Boss has a global ranking, and it is off until you switch it on. While it is off, ThinkMantis sends nothing about you anywhere: it makes no request to us at all, and every other part of the game works exactly the same.
If you do switch it on, finishing a Weekly Boss run sends your score, a handle we generate for you (something like SwiftLantern42), and a random player id created on your device. The handle is what appears on the board. You cannot put your own words on the leaderboard, so nothing you type can end up in public — and the nickname you give the coach stays on your device and is never sent. The player id travels in the request itself rather than in the web address, so it does not end up in ordinary server logs, and it is never shown to anyone.
Those scores are kept for the week they belong to and are deleted automatically about six weeks later. What travels with a run is the score, the generated handle, the random player id, whether you finished the run, how each stage went — hit or miss and the time left — and your run totals: attempts, hits, stages cleared, lives left and accuracy. Those last two parts are what stop a made-up score ranking above a real one. Nothing else goes with them: no email, no device details, no record of which answers you picked, and nothing you typed.
You can turn Global Rank off again at any time from the rank panel or in Settings.
Duel links you send.
You can challenge a friend by sending them a link. The link carries the game, the score to beat, and a name you choose to show them — the field asks for a nickname rather than your real name. That name is kept on your device and written into the link; it is never sent to us. It also sits in the part of a web address that browsers do not send to a server, so it does not end up in server logs. It is still a link, though: anyone who has it can read it, so send it only to people you mean to.
The one thing every website sees.
Loading ThinkMantis the first time means asking a web server for it, and — like every website on the internet — that server sees the request: your IP address, the browser you are using, and what you asked for. We do not use that to build a profile, and after the first load the game keeps its own copy on your device, so it can run with no connection at all. We mention it because "nothing leaves your device" would not be quite true otherwise.
Works offline.
ThinkMantis works offline. It keeps a copy of its own files on your device so a run works with no connection. That copy lives only on your device and contains the app itself, not information about you.
Voice.
The spoken commentary is written by us and spoken by your own device: ThinkMantis hands a sentence to the speech voice built into your browser. It asks for a voice that runs on the device, so nothing is sent anywhere. A few browsers only offer cloud voices; on those, your browser — not ThinkMantis — sends that sentence to its own speech service to turn into sound, and if you have given the coach a nickname it may be in that sentence. You can switch commentary off entirely in the audio settings. ThinkMantis never uses your microphone and never records anything you say.
Written for ages 13 and up.
ThinkMantis is designed for players aged 13 and up. That is a statement about the content — fluent reading, everyday adult situations, and timed play — not about data. With Global Rank off — the default — the game sends nothing about a player anywhere: everything it remembers stays in that browser, on that device. With Global Rank on, the only thing that leaves the device is a Weekly Boss result, exactly as described above. Nothing else is gathered from anyone who plays, whatever their age.
There is nothing to buy.
ThinkMantis is free to play right here in your browser — no account, no ads, and nothing sold inside it. Because nothing is sold, there is no payment to take: Switik never sees a card number, a billing address or any payment details, and there is nothing for us to store about one.
Changes to this policy.
We may update this page as the game evolves. The build stamp in the footer reflects the current version. If we ever change how data is handled, we'll update this page to match.
