Privacy Policy

Effective date: July 23, 2026

WikiSys is built around one idea: your wiki is your data, in your own storage. Each wiki is a markdown file in a Google Drive folder that you own. WikiSys has no user accounts, no server-side database, and keeps no copy of your content. This page explains exactly what information the service touches and why.

What WikiSys stores

• Your wiki content is stored only in your Google Drive and in your own browser (a working cache in IndexedDB, plus per-wiki settings such as folder links and sync timestamps in localStorage). It is never written to WikiSys servers.
• WikiSys servers store no user records. There is no signup, no account database, and no analytics or advertising tracking on the site.

Google account and Drive access

Signing in uses Google's own sign-in flow and requests a single scope, drive.file — the narrowest Drive scope. It lets WikiSys see and edit only files and folders that WikiSys itself created (or that you explicitly opened with it). It cannot browse the rest of your Drive. The access token stays in your browser; WikiSys servers never receive or store it.

WikiSys's use and transfer of information received from Google APIs adheres to the Google API Services User Data Policy, including the Limited Use requirements. Your Drive data is used only to provide the wiki features you invoke — reading and saving your wiki files — never for advertising, profiling, or training, and is never sold or transferred to third parties.

Share links

When you create a share link, your Drive folder's location is encrypted into the link itself using a server-held secret. Recipients interact with the wiki through the WikiSys server, which relays reads and writes to your Drive folder without ever revealing its location. In doing so the server handles your wiki content transiently, in memory, per request — it does not retain it. Link passphrases are never stored anywhere: they are used only to derive cryptographic keys, and verification happens without keeping the passphrase.

Who can actually read or edit a shared wiki is always governed by your Google Drive folder's own sharing permissions — revoke them in Drive and every link stops working.

Server logs

Like nearly all web services, the WikiSys server (hosted on Google Cloud Run) produces standard request logs — IP address, requested URL, user agent, timestamp — used solely for operating the service, debugging, and abuse prevention (rate limiting). Logs are retained per Google Cloud's default retention and then discarded. Wiki content and passphrases are not logged.

Cookies and third parties

• WikiSys sets no cookies. All local state lives in your browser's localStorage and IndexedDB, which you can clear at any time.
• Pages load fonts and open-source libraries from public CDNs (Google Fonts, and CDN-hosted copies of Tailwind, marked, highlight.js, and Lucide). Those providers receive the standard technical data of any web request (such as your IP address).
• Google's sign-in and Drive services operate under Google's own privacy policy.

Deleting your data

• Content: delete the wiki's folder in your Google Drive. WikiSys holds no other copy; existing share links stop resolving.
• Access: revoke WikiSys's Drive permission at myaccount.google.com/permissions.
• Local cache: clear site data for wikisys.com in your browser.
