Privacy

The short version: we never see your files.

Your files stay on your device

Every tool on Opener runs inside your web browser. When you open a PDF, a spreadsheet, a presentation or any other file, it is read by your browser and is never sent to us or anyone else. We have no server that could receive it.

No accounts

There is nothing to sign up for, so we do not collect names, email addresses or passwords.

What stays in your browser

Your browser remembers which language you prefer. This is stored only in your browser and never sent to us.

What our hosting provider sees

Like any website, the pages are delivered by a hosting provider that processes standard technical data such as IP addresses to serve pages and protect against abuse. This data is never combined with anything you open in the tools.

Visit statistics

We count visits with Cloudflare Web Analytics to learn which tools are useful. It sets no cookies, does not follow you across sites and does not build a profile of you — we only see totals such as page views, countries, browsers and which site sent you. It never sees the files you open.

Changes

If we ever add advertising or change how we count visits, this page will be updated before it goes live.
