Privacy policy
Last updated: July 2026
WikiTaka is a discovery feed for Wikipedia articles. This page explains what data we handle, why, and the controls you have. We collect the minimum needed to run the service; no data is ever sold or shared with third parties for their own purposes.
What we store
An account identifier (created silently for guests; email and password hash if you register), your profile preferences (nickname, languages, theme, timezone — the timezone keeps streaks fair), your reading activity (which articles you view, read, like, save, share, or dismiss, with timestamps), an interest profile derived from that activity (per-topic scores that power your feed), your exploration journeys (the trail of articles you follow in a dive, kept so you can resume, edit or delete them), your collections (named folders that group saved articles and journeys), gamification progress (XP, streaks, badges, quiz and daily-quiz answers, per-day activity summaries) and any page suggestions you submit.
Why we store it
Reading activity powers your personalised feed: it is the product. Preferences keep the app in your language and theme. When semantic features are enabled, article summaries and your search text are turned into numeric vectors (embeddings) by the configured AI provider to find related pages — no account data rides along with those requests. We do not use any of this for advertising profiles and we do not track you across other sites.
What others can see
Nothing, unless you choose to share it. The weekly leaderboard shows your nickname and weekly XP to other users — you can opt out in Settings. Publishing a journey or a collection creates an anonymous, read-only public page under a random link (with a view counter); you can unpublish it at any time. The most-visited published pages are ranked on a public chart — this week, this month and all-time — built only from page-view counts per shared item, never from who visited or who shared them; a link-only option in every share menu keeps yours reachable by URL but out of the chart, the landing teaser and search engines. Shared article links never include your browsing trail.
Optional features & third parties
If you opt into streak reminders, this browser's push subscription (a technical endpoint, no personal data) is stored until you disable them or delete your account, and is used only for that one evening notification. Quizzes are AI-generated by the configured language model. When enabled, cookieless analytics (Umami) measures aggregate traffic and anonymous product events (pages viewed, reads completed, and similar) — no cookies, no cross-site tracking, no personal identifiers — and an error-reporting service (Sentry) receives crash reports. If you leave your email to hear about Premium, we store only that address and your interface language, use them solely to contact you about Premium, and delete the entry when you delete your account or ask us to. Some article pages may show clearly labeled affiliate links: the outbound retailer link carries our affiliate tag, and no personal data is shared with the retailer.
Cookies
We set one strictly necessary session cookie so the app knows who you are; no consent banner is required for it. Preferences such as theme and your consent choice itself live in your browser's local storage, never on our servers. Analytics, when enabled, is cookieless (see the section above). If advertising is ever enabled, ad scripts load only after you explicitly accept them in the consent dialog; rejecting keeps the app fully functional and ad-script-free, and you can review or change your choice at any time right below.
Retention
Data is kept while your account exists. You can remove items yourself at any time — unsave an article, remove one reading-history entry or clear the whole history, delete a journey or a collection (clearing history leaves your saved items, likes, XP and interests untouched). Deleting your account removes your profile, preferences, saved articles, collections, journeys, XP and badges immediately; behavioural events are anonymized (unlinked from any identifier) and kept only as aggregate statistics.
Your rights (GDPR)
You can access and export everything we hold about you from Profile → Privacy & data (a JSON download), and erase your account from the same place; both are self-serve and immediate. You may also lodge a complaint with your local data-protection authority.
