Privacy
Last updated: 23 October 2026
Comparle is made and run by a private individual in the Netherlands — below, "the person running Comparle", the controller of the data described here. Questions or requests: contact@comparle.app.
Short version: you can play without an account, no data is sold, no ads, no third-party trackers.
What is stored, why, and for how long
| What | Why | How long |
|---|---|---|
| Player id — a random number your browser keeps | to find your own games and streak without an account | as long as you leave it in your browser; clear it and the link is gone |
| Game results — score per round, gamble, word, date, edition | the game itself: score, streak, stats, pool standings | with the player id; with an account, until you delete the account |
| Account — e-mail address, display name | logging in, your progress across devices | until you delete the account at my.comparle.app/account |
| Sessions — one login token per device | keeping you logged in | 90 days, or until you log out or delete the account |
| Login links and codes | to let you in once | short-lived, then gone |
| Pools — name, members, standings | making the pool work | until the pool is deleted |
| Settings — language, theme, share-card style | keeping the game the way you like it | with your player id or account |
| Reminder (web push) — only if you turn it on yourself: the address your browser gives for notifications, the hour you chose, your player id | sending you one nudge a day when the new word is up, and none if you already played that day | until you turn it off (⚙ → Notifications, or in your browser), or until your browser withdraws the address |
| Review notes — only when review mode is on: your remark plus the on-screen context | to fix what you report | until the remark is resolved |
| Technical events — errors, timestamp, the country the Cloudflare network sees | finding outages, slowing down abuse | briefly, and in aggregate |
Legal grounds
Your account and your games belong to the agreement you have with Comparle (contract). Technical events, abuse prevention and anonymous visit statistics rest on the legitimate interest of keeping the game working and safe. Review notes are something you send yourself.
Cookies
Three things, and none of them follows you around the web:
- `sess` — only if you log in: keeps you logged in (90 days).
- `lang` — remembers which edition you play (nl or en).
- Local storage in your browser — your player id, your settings, your game progress.
There are no advertising or tracking cookies. Visit statistics run through Umami, which works without cookies and is self-hosted on the owner's server (stats.comparle.app). It counts pages and visits, not people. When a link carries a campaign label (utm_source and the like), or you arrived through a shared result on www.comparle.app, the game counts that label. Who shared the link is not recorded.
Who processes it
- Cloudflare — hosting, database (Workers and D1), network, and sending the login mails. On servers in Europe and the global edge network.
- Umami — visit statistics, self-hosted by the owner; not a third party.
- Your browser's push service (for example Google, Mozilla or Apple) — only if you turn on a reminder: it delivers the message. The message is encrypted; the service sees that a message arrives, not what is in it.
- Alldle (alldle.net) — the small "Play on Alldle" badge on the English pages is an image loaded from Alldle's server, so Alldle sees the IP address and page address of every visit to those pages, like any image from another site. Nothing else is sent; the badge sets no cookie. Alldle also lists Comparle on its own site and plays it there inside a frame. When you play Comparle inside Alldle's page, signed in to Alldle or not, each word you play is reported to Alldle: that you started it and finished it, your score, the row of coloured squares, the day or word number and how long it took, with a random number the game keeps in your browser so a result counts once. No personal data, no word, no answer and no account of ours goes with it. Alldle receives this under its own privacy policy and uses it for its streaks, result cards and statistics. When you play on comparle.app itself, nothing is sent to Alldle at all.
Nobody else. No data is sold or shared for advertising.
Children
There is no age gate, and deliberately as little data is asked as possible: you can play without an account. If you are a parent or guardian and want your child's data removed, e-mail contact@comparle.app.
Your rights
You may see what is held about you, have it corrected, deleted or handed over, and object to its use.
- Deleting you do yourself, right away: my.comparle.app/account → delete account.
- For everything else: e-mail contact@comparle.app. You get an answer within a month.
If you disagree with how your request was handled, you can complain to the Dutch data protection authority, the Autoriteit Persoonsgegevens (autoriteitpersoonsgegevens.nl), or the one in your own country.
Changes
If something important changes, the date at the top moves and it is announced in the game.
