Privacy policy
What the Dojo keeps about you, why, for how long, and how to erase it all.
Last updated: 3 October 2026. This is a translation; in case of discrepancy, the French version prevails.
Who is responsible?
The Dojo team — dojolinux@gmail.com (see the legal notice).
What the Dojo collects, and why
| Data | Why | Legal basis | Retention |
|---|---|---|---|
| E-mail, nickname | Create your account, sign you in (e-mail link or Google), show you in the Dojo | Contract (providing the service) | As long as your account exists; deleted after 3 years without sign-in |
| Progress (exercises, challenges, labs, exams, active days for the 🔥 streak), name on the certificate | Find your progress on all your devices, issue and verify your certificate | Contract | As long as your account exists |
| E-mail, nickname and date entered when entering the Dojo | Track sign-ups (list kept in Google Sheets) | Legitimate interest | 3 years after the last visit |
| E-mail, only if you ticked “Tell me when the Cisco Dojo and the next Dojos come out”, and the date of your consent | Announce new Dojos (Cisco Dojo…) to you by e-mail | Your consent, which you can withdraw at any time | Until you withdraw your consent |
| E-mail, date of last activity, only if you accepted “Send me an e-mail if I take a break”, and the date of your answer | Send you at most 3 reminder e-mails when you stop practising (“We miss you…”) | Your consent, which you can withdraw at any time | Until you withdraw your consent |
| Feedback message on an exercise | Fix and improve the exercises (sent from your own mail app) | Legitimate interest | 3 years |
No ads, no ad trackers, no data resale. The Dojo only sends you announcements (Cisco Dojo release, new Dojos) if you ticked the box for it, which is never ticked in advance. To withdraw your consent: untick “Tell me about new Dojos” in your profile (☁️), click the unsubscribe link in every e-mail, or write to dojolinux@gmail.com. Same for reminder e-mails: untick “Send me an e-mail if I take a break” in your profile (☁️) or use the link in every e-mail.
Cookies and browser storage
dojo_atcookie: keeps your session so the site knows you are signed in and sends you the full Dojo. Essential to the service, it expires after one hour at most.- Local storage (
localStorage): your progress, nickname, e-mail and sign-in session, so the Dojo works even offline.
These are strictly necessary for the service and need no consent (Belgian Electronic Communications Act of 13 June 2005). The Dojo uses no analytics or advertising cookies.
Who receives your data
- Supabase (accounts, progress, certificates, purchases): data stored in Europe.
- Brevo (Sendinblue SAS, Paris, France): sending reminder e-mails, only if you accepted them.
- Netlify (website hosting): receives your IP address on each visit.
- Google: sign-up list (Google Sheets), Google sign-in if you choose it, and the Dojo’s fonts (Google Fonts, which receives your IP address).
- jsDelivr (content delivery network): serves the sign-in library and receives your IP address.
- Discord (community): only if you choose to join the Dojo's Discord server. Your exchanges there are governed by Discord's privacy policy; the Dojo sends it no data.
Some of these providers are based in the United States. Transfers rely on the EU–US Data Privacy Framework or on the European Commission’s standard contractual clauses.
Your rights
At any time you can access, correct, erase or export your data (portability), object to or restrict its processing. Write to dojolinux@gmail.com; we answer within one month. Deleting your account erases your progress, certificates and access.
If you believe your rights are not respected, you can lodge a complaint with the Belgian Data Protection Authority (rue de la Presse 35, 1000 Brussels) or the authority of your country.
