Privacy Policy

Last updated: 17 April 2026. Applies to onlineoffice.app and all sub-pages.

Summary

OnlineOffice is a collection of office tools (PDF, viewers, converters, unit converter, crypto helpers, …) that run entirely inside your browser. The documents, images and text you process never leave your device — there is no upload, no server-side conversion, and no account system.

1. Controller

Controller within the meaning of Art. 4 No. 7 GDPR is:

2. What data is processed

2.1 Server logs

When you visit the site, the hosting provider records access data (IP address, user agent, referrer, requested URL, timestamp) in server log files. This is necessary to deliver the page and to defend against abuse (Art. 6 (1) (f) GDPR — legitimate interest). Logs are kept for a maximum of 14 days and then deleted or anonymised.

2.2 Files you process inside the tools

Every tool on this site runs client-side as JavaScript / WebAssembly. That means:

• Your files are read into the browser's memory with the native File API.
• All processing (PDF editing, conversion, viewing, hashing, …) happens in the browser.
• No file content, filename or metadata is transmitted to any server operated by us.

Some tools use external content delivery networks (see section 3) to load third-party libraries — these CDNs only see that a library was requested, never your files.

2.3 Local storage

To keep preferences between visits, OnlineOffice uses the browser's localStorage for:

• Your theme selection (system / light / dark).
• Your dismissal of the storage notice (so the banner isn't shown on every visit).
• Per-tool preferences (active tab, last-used unit, recently opened document metadata — no file content).

These entries are stored only on your device. You can clear them at any time via your browser's settings.

2.4 Service worker / offline cache

A service worker (sw.js) caches the static HTML, CSS and JavaScript so the tools keep working offline. The cache is re-validated on each visit and contains no personal data.

3. Third-party resources

A few tools load their engines from public CDNs the first time you open them. Your browser will make an HTTP request to these domains, which could include your IP address:

• cdn.jsdelivr.net — PDF.js, PPTXjs, SQL.js, Three.js loaders and similar helper libraries.
• unpkg.com — occasional fallback for the above libraries.

Loading these libraries is necessary to provide the respective tool feature and relies on legitimate interest (Art. 6 (1) (f) GDPR). No cookies are set by these CDNs; they do not profile the visitor.

The site is hosted at a commercial hosting provider and uses standard HTTPS / TLS. No analytics service, tag manager, advertising network or social-media pixel is embedded.

4. Cookies

OnlineOffice does not set any tracking or advertising cookies. The only persistent browser storage is the localStorage entries described in section 2.3 — these are technically required to remember your theme and to keep the cookie banner dismissed.

5. Your rights (GDPR)

You have the following rights concerning the personal data we process (mainly: server log entries):

• Right of access (Art. 15 GDPR).
• Right to rectification (Art. 16 GDPR).
• Right to erasure (Art. 17 GDPR).
• Right to restrict processing (Art. 18 GDPR).
• Right to data portability (Art. 20 GDPR).
• Right to object to processing (Art. 21 GDPR).
• Right to lodge a complaint with a supervisory authority (Art. 77 GDPR).

To exercise any of these rights, contact me at onlineoffice.direction095@passmail.com.

6. Changes to this policy

The policy can be updated to reflect changes in the service or in the legal landscape. The version currently in force is always the one published here; the "Last updated" date above reflects the latest change.
