Privacy policy
Effective 6 October 2026
The short version
- Krisox compresses and converts files inside your browser. Your files, their names and their contents are never sent to us. There is no Krisox server that could receive them.
- The Krisox extension makes no network requests. It collects no analytics, shows no ads and includes no tracking.
- Your settings and license key stay in your browser.
Your files
When you upload a file on a website, Krisox reads it inside that browser tab so it can show you the size at each compression level, and compress or convert it if you choose. Results are kept in the tab's memory only until you upload, download or cancel, and are then discarded.
The file you choose to upload (the original or the smaller version) is sent only to the website you were uploading it to, by that website, as it would be without Krisox. What that website does with it is covered by its own privacy policy.
What Krisox stores on your device
- Your settings, including the sites you turned Krisox off for. They are saved with Chrome's extension storage. If you use Chrome sync, Google syncs them between your browsers as part of your Chrome data. Krisox does not receive them.
- A running total of space saved and the number of files compressed, on this device only.
- Your license key, if you activate Krisox Pro. The key contains the email address or order ID it was issued to, your plan and its expiry date. It is stored and checked on this device only.
You can reset the total and remove your license in the extension's settings. Uninstalling Krisox removes all of it.
What Krisox sends over the network
Nothing. Krisox does not contact any server, ours or anyone else's. Links in the extension, such as "See plans", open this website in a tab like any other link.
Permissions, and why Krisox needs them
- Runs on all websites, so it can notice when you upload a file, wherever that happens. It looks only at the files you choose to upload. It does not read or record the pages you visit.
- Storage, to save your settings, your space-saved total and your license key.
- Active tab, so that when you open the Krisox popup it can see which site you're on and let you turn Krisox off there.
Buying Krisox Pro
Krisox Pro is sold through Paddle, which acts as our reseller and merchant of record: Paddle processes your payment and handles taxes, under Paddle's privacy policy. We never see your card details. Paddle shares your email address and order details with us so we can send your license key (including a new one each time your subscription renews) and help with refunds and support. We use them for nothing else, and we never sell them.
This website
This website uses no cookies and no analytics. It loads no third-party scripts until you click a "Get Pro" button, which loads Paddle's checkout. Like any website, its hosting provider may keep standard server logs (such as IP address, browser type and pages requested) to operate and secure the site.
Children
Krisox is not directed at children under 13, and we don't knowingly collect information from them.
Your rights and questions
To ask what we hold about you, or to have your purchase records deleted, email [email protected].
Changes
If Krisox starts collecting any new kind of data, we will update this policy, and its effective date, before that happens.
