Privacy Policy

Effective 15 October 2026

All data is stored locally on your computer. ClicknFill has no servers and no accounts. It does not collect, sell, share or send your personal data anywhere.

What ClicknFill stores on your computer

Everything below is saved with the browser's extension storage (chrome.storage.local) on your device only:

• Profiles you create: names, parents' and spouse's names, date of birth, gender, category, contact details, addresses, education, any ID numbers you choose to save (for Aadhaar, only the last 4 digits), and custom fields.
• Fields you teach it: the website address, a technical reference to the form field, and which profile item fills it.
• Fill history: for each fill, the website address and page title, the time, which profile was used (as an internal id, not the name), how many fields were filled, and the labels of fields that weren't. The newest 300 fills are kept, and you can clear them at any time.
• Settings, such as which profile is active.

If you set a PIN, your profiles are encrypted (AES-GCM, 256-bit) with a key derived from your PIN (PBKDF2, 310,000 iterations). The unlocked key is kept in memory only and is cleared when you close the browser. Your PIN itself is never stored.

What ClicknFill does not do

• It does not send your profile data, photos or anything else off your device.
• It has no analytics, tracking, advertising or third-party code, and loads no remote code.
• It does not read web pages in the background. It works on a page only when you click Fill this page, press the keyboard shortcut or choose it from the right-click menu, and then it reads only the form fields on that page to fill them.
• It never submits forms and never touches password, OTP or CAPTCHA fields.

Photos and signatures

The resizer works entirely inside your browser. Images are never uploaded and ClicknFill does not keep them; the resized file goes to your Downloads folder.

To change a photo's background, ClicknFill uses an AI model (Google MediaPipe Selfie Segmentation) that is included in the extension and runs on your computer. Your photo is not sent anywhere, and the model is not downloaded from the internet. Signatures you draw on the signature pad stay on your computer too.

If you take a photo with your camera in the resizer, Chrome asks your permission first. The camera is only on while the camera view is open; the picture you take stays on your computer like any other photo, and nothing is recorded or sent anywhere.

Backup files

A backup file is created only when you choose Export profiles. It is encrypted with the password you choose, and you decide where it goes.

Permissions

• storage: to save your profiles and settings on your computer.
• activeTab: to access the current tab only when you click the toolbar button or press the shortcut.
• scripting: to add the form filler to that tab at that moment.
• Keyboard shortcut (Alt+Shift+F): to start a fill from the keyboard.
• contextMenus: to add a ClicknFill item to the right-click menu on form fields. The menu lists your saved details so you can fill one field; it is part of the browser, not the web page, and websites cannot read it.

Deleting your data

Delete profiles, learned fields and fill history from ClicknFill's settings page at any time. Removing the extension deletes everything it stored.

Changes

If a future version needs the internet, for example to check a paid licence, this policy will be updated before that version is released. Your profile data will still never leave your device.
