Privacy policy
Updated: 21 October 2026
You can use Dialectio without an account. We use no tracking cookies and share no data with ad networks.
Visit statistics
To learn which words people find interesting, we count page views with Umami, running on our own server. It uses no cookies, stores no IP addresses and does not follow you across sites: we only see totals — how often a page was opened, from which country and which site.
Search
When a search finds nothing, we keep the search text and a counter so we can add the word to the dictionary. Nothing about you is stored with it.
When you add a word
We store what you enter in the form: the word, the language or dialect, the place and a voice recording (optional), and that your account sent it. After review, the name of your account and the place may be shown next to the word. By sending a contribution you allow Dialectio to publish it.
When you vote or report a mistake
We store your vote (yes or no) and the text of a mistake report. So that one browser has one vote per word, your browser creates a random id; the server keeps only its hash, which cannot be turned back into the id. The region, if you gave it, is stored with the vote and helps refine the dialect map.
IP address
To fight spam, the server temporarily remembers how many contributions, votes and reports came from an IP address (in the last hour or day). This is not written to the database.
In your browser
The site remembers in your browser (localStorage) the dialect you last picked in the contribution form, your votes, your region and a random id for voting. Apart from the votes, this is not sent to us.
Third-party services
The basemap is loaded from OpenFreeMap servers and some audio from Wikimedia Commons. These services see your IP address, like any site your browser loads something from. To keep bots out, the sign-up, email and add-a-word forms are checked by Cloudflare Turnstile: it sees your IP address and technical browser data, but sets no advertising cookies.
If you sign up
We keep your email address, your name and a hash of your password (the password itself is neither stored nor recoverable from the hash). If you sign in with Google, Google gives us only your (verified) email address and your name; no password is needed then. After signing in, the browser gets a session cookie, used only to keep you signed in. Your votes and control-card answers are linked to the account. You can delete the account in your profile: email, name and sessions go at once, votes stay anonymous. The languages and dialects in your profile and your speaker test results are kept with the account and deleted with it; words you added stay on the site without your name. Emails (confirming your address, a new password, sign-in links) are sent through Brevo (Sendinblue SAS, France): it receives only your address and the email itself. If you apply to be an expert, we keep your application text; what an expert does to words is written to the change log with their name.
Deletion
To delete your contribution or voice recording, write to us on GitHub with the word and the dialect.
