Cookie Notice
Effective 11 November 2026
In short
- Hopfluent uses one cookie, and only to save your progress.
- It is set when you complete your first lesson or practice question, not when you merely visit.
- There are no advertising, analytics or third-party cookies, so there is nothing to opt out of.
This summary is here to help. The full text below is what applies.
On this page
1.What is stored in your browser
| Name | Type | Purpose | Lasts |
|---|---|---|---|
hf_sid | Cookie, strictly necessary | A random identifier that links this browser to your saved progress, or keeps you signed in if you have an account. It is not readable by scripts and is sent only to Hopfluent. | Up to 400 days, renewed while you use the Service, or until you sign out or delete your data |
hf-progress-v2 | Local storage, strictly necessary | A copy of your progress, the email address of the account you are signed in to, and any results not yet sent, so lessons respond instantly and work on a poor connection. | Until you sign out, delete your data or clear your browser storage |
hf_oauth, hf_gticket | Cookies, strictly necessary | Set only if you choose to sign in with Google. They carry the sign-in safely across the trip to Google and back, and are not readable by scripts. | At most ten minutes; removed as soon as sign-in completes |
hf-lesson-…, hf-attempt-…, hf-plus-next | Session storage, strictly necessary | Your place in a lesson you have not finished, and a signed note of when you opened it, so a refresh does not lose your work and the time taken can be checked. | Until you finish the lesson or close the tab |
hf-theme | Local storage, a display setting you choose | Remembers whether you chose the light, dark or system theme. It never leaves your device. | Until you clear your browser storage |
2.Why there is no consent banner
The cookie and the progress copy are strictly necessary to provide a feature you ask for: saving your progress. The theme entry only stores a display setting that you choose yourself, and it never leaves your device. The law does not require consent for storage of these kinds. We do not use anything else.
3.What we do not use
- Advertising cookies.
- Third-party analytics or tracking scripts.
- Social-media pixels or embedded trackers.
- Fingerprinting or any other technique for recognizing you across websites.
4.Your control
You can erase your saved progress, and with it the cookie, from Settings. You can also block or delete cookies and site data in your browser. If you do, the Service will still work, but your progress will not be kept between visits.
5.Changes
If we ever want to store anything that is not strictly necessary, we will ask for your consent first, it will be off until you agree, and this notice will be updated. Questions can be sent to privacy@hopfluent.com. See also our Privacy Policy.
