Privacy Policy
Last updated: November 13, 2026
Vocadawn of Offlinova is a free vocabulary flashcard app that runs in your web browser. This policy explains what happens to your information when you use it.
Data collection
There is no account, no sign-up and no login. Vocadawn of Offlinova does not ask for your name or email address and does not run a mailing list or newsletter.
Your study progress — which words you have studied, their review dates, your grades, your notes, your daily counts and your settings — is stored only on your device, in this browser’s IndexedDB (or localStorage if IndexedDB is not available). It is not sent to us, and we do not run a server-side database of users. Your language choice is also remembered in the browser.
The daily reminder is a calendar file (.ics) that the app creates on your device. If you add it to your calendar, your calendar app shows the reminder. We do not send notifications and we do not run a push server.
Pronunciation uses your browser’s built-in speech feature (Web Speech API). Depending on your browser and operating system, some voices are online voices provided by the browser maker (for example Google or Microsoft), in which case the word being read is sent to that company to produce the audio.
When you visit the website, pages are served through Cloudflare. Like most sites hosted this way, Cloudflare may keep standard request logs, which can include your IP address, browser user agent, date and time, and the address you requested.
We do not run Google Analytics or any analytics product of our own, and there is no analytics tag in the Vocadawn of Offlinova source files. Cloudflare Web Analytics is enabled as a zone setting for offlinova.app, so Cloudflare may add its measurement script (from static.cloudflareinsights.com) to the pages. Cloudflare describes it as privacy-first analytics without cookies; we have not independently audited it.
Third parties
- Hosting and content delivery: the website is hosted on Cloudflare Pages. Cloudflare processes the technical request data described above to operate, secure and measure the service.
- Advertising: the website loads Google AdSense and may show ads. Google and its partners use cookies and similar technologies, and may serve personalized ads based on your visits to this site and other sites. The AdSense script also loads related Google advertising resources (for example from googlesyndication.com, doubleclick.net and adtrafficquality.google).

Opt out / unsubscribe
Because Vocadawn of Offlinova does not collect email addresses or run a mailing list, there is no newsletter subscription to cancel.
To opt out of personalized advertising, use Google Ads Settings or the industry opt-out pages below. In the European Economic Area, the United Kingdom and Switzerland, Google shows personalized ads only with your consent.
To delete your study progress, open Settings in the app and choose “Reset all progress”, or clear this site’s data in your browser settings. That removes the only copy; we do not have another one. To stop a calendar reminder, delete the event in your calendar app.
For any other request, including opting out, email [email protected] (this link includes the subject “Unsubscribe”).
Cookies
The Vocadawn of Offlinova app itself does not set cookies. It uses on-device storage (IndexedDB and localStorage), which is not a cookie, to keep your progress and settings. Google AdSense may set cookies and use similar technologies, as described in Google’s policies. You can block or delete cookies in your browser; clearing this site’s data also deletes your study progress on that device.
Children
This site is a study tool for teenagers and adults preparing for English exams and is not directed at children under 13. We do not knowingly collect personal information from children; study progress stays on the device.
International users (GDPR and CCPA rights)
If you are in a region that grants rights such as access or deletion under the GDPR, the UK GDPR or the CCPA: we do not hold your study data on a server, so there is no record of yours for us to export or erase. You can export a backup and delete your data in the app, or by clearing this site’s data in your browser. For technical logs or advertising data held by Cloudflare or Google, see their policies. You can also contact us at [email protected].
Changes to this policy
If this policy changes, the new version will be posted on this page with a new date.
