Privacy policy

Who is responsible

The publisher of KeyBrief, introduced in the legal notice, is responsible for the processing described here. For any question or request about your data: To be completed by the owner.

Legal bases: providing the service you ask for when you sign in (account, import and tracking of your characters), and KeyBrief’s legitimate interest in measuring its audience, fixing its errors and protecting the site.

Without an account

You can read the whole site without an account, and without any cookie. Your guest progress stays in your browser’s local storage; it is sent to KeyBrief only if you sign in, to attach it to your account.

Battle.net data

You sign in with Battle.net: you enter your credentials at Blizzard only, and KeyBrief never sees or keeps your password. Once you give your consent at Blizzard, KeyBrief receives your Battle.net account identifier, your BattleTag and an access token valid for 24 hours, stored encrypted, then imports your characters: talents, gear and Mythic+ profile (rating and best keys).

Blizzard remains responsible for your Battle.net account, under its privacy policy.

History and original data

From this data, KeyBrief keeps your Mythic+ history: each time one of your best runs changes, it records it (dungeon, level, timed or not, duration, date, affixes, rating at the time, and your teammates’ class and spec, never their names), and it keeps one snapshot of your rating per day. Your original data is what you create on the site: progress, practice cards, notes, preferences and reports.

How long data is kept

• Data from the Blizzard API (characters, talents, gear, Mythic+ profile): refreshed every day, and deleted 30 days after their last refresh. Raw responses from the API are deleted after 30 days.
• Mythic+ history: kept as long as the character is linked to your account.
• Original data: kept until you delete your account.
• Backups: the database is backed up every day, and each backup is deleted after 30 days.

Unlink or delete

From your account, “Unlink Battle.net” immediately deletes your characters, talents, gear, Mythic+ profiles and history, and your Battle.net tokens. “Delete my account” deletes everything, original data included, and ends all your sessions. Deleted data leaves the backups within 30 days.

Cookies

Only if you sign in: session cookies, strictly necessary to sign you in and keep you signed in. A session ends when you sign out, or 30 days after your last visit; KeyBrief ties neither your IP address nor your browser to it. No analytics or advertising cookie, hence no consent banner.

Cookieless analytics

KeyBrief measures its audience, records browsing sessions (replays) and tracks its errors with PostHog Cloud EU, hosted in Frankfurt, set up without cookies: nothing is stored in your browser for this purpose. This data serves only to fix errors and improve the site, and is kept for To be completed by the owner.

Hosting and service providers

The site and its database are hosted in Europe, on an OVH server. The other providers are Cloudflare (delivery of the site and storage of backups), PostHog (analytics and errors) and GitHub: a report creates an issue in the project’s private repository, with the guide, spec, character and game build concerned. Your data is neither sold nor used for advertising.

Your rights

You can access your data, correct it, delete it, obtain a portable copy, object to its processing or ask for it to be restricted. Deletion is self-service from your account; for the rest, write to To be completed by the owner. You can also lodge a complaint with the CNIL, the French data protection authority.
