SizeFit

Privacy policy

Effective 25 October 2026

The short version

The SizeFit app

Your files

All compression and verification happens on your device using Apple’s system frameworks. SizeFit opens the files you give it read-only and writes new files only to the folder you choose (on Mac, Downloads by default; on iPhone and iPad, SizeFit’s own folder in the Files app). Nothing is uploaded.

Photos (iPhone and iPad)

Videos you pick from Photos are copied into SizeFit with the system photo picker, which doesn’t give the app access to the rest of your library. “Save to Photos” asks for add-only access, used solely to save the compressed video you chose to save.

Network access

The app makes one kind of network request: it downloads the public list of platform size limits from sizefit.app/presets.json so presets such as “Discord 20 MB” stay current. The request contains no account, device identifier or information about your files — only the standard data any web request includes (such as your IP address, which our hosting provider may process to deliver the file and protect against abuse). The app works fully without it.

Purchases

SizeFit Pro is sold through the App Store. Apple processes the payment; we don’t receive your name, payment details or Apple ID. The app checks your purchase locally using Apple’s StoreKit.

Analytics and crash reports

The app contains no analytics or tracking SDK. If you have opted in to share diagnostics with app developers in your device’s settings, Apple may provide us with anonymous crash reports.

Launch waitlist

If you enter your email in the “Get notified” dialog, we store it with the date, which price you were shown, and the campaign tags in the link you followed (for example utm_source). We use it only to email you when SizeFit launches. We never sell or share it. To have it deleted, email us (see Support); we’ll also delete the list once the launch campaign is over.

To prevent abuse we keep a one-way hash of your IP address that changes daily; we do not store the IP address itself.

Product page measurements

We are testing how people respond to the product page and price. Your browser keeps a random identifier and the price variant it was shown in local storage (not a cookie). With it we count page views and clicks on “Get SizeFit”. These events contain no personal information and are not combined with other data.

If your browser sends Do Not Track or Global Privacy Control, we don’t record these events at all. You can also clear the identifier at any time by clearing this site’s data in your browser.

Hosting

The website runs on Cloudflare, which processes request data (such as IP addresses) to deliver pages and protect the site, under its own privacy policy.

Children

SizeFit is not directed at children under 13, and we don’t knowingly collect their information.

Changes and contact

If this policy changes, we’ll update the date above. Questions or deletion requests: see Support.
