Privacy policy

Last updated: November 11, 2026

Draft. This policy has not yet been reviewed by a lawyer or adviser, and it does not replace professional legal advice. It should be reviewed before the website and the app are published.

In short

• No uploads: your screenshots never leave your Mac through the app.
• No cloud processing by ShiftCommand4. The app has no network permission.
• No accounts, no tracking and no advertising.
• No third-party AI services: only Apple's text recognition and Apple's on-device model, on your Mac.
• Nothing from your screenshots (images, text, titles or history) is sent to the developer.

Who is responsible

ShiftCommand4 is developed and operated by Cesar Pedro Julian Ibañez (NIF 46343787Y), under the name Pepemundo, based in Barcelona, Spain. Postal address: Apartado de correos 6015, 08022 Barcelona, Spain.

Part 1 — The app

What it does

ShiftCommand4 reads the text in your new screenshots and writes a title for them. It does this on your Mac, using Apple's text recognition (Apple Vision) and Apple's on-device language model (through Apple's Foundation Models framework). When there is little text, it may also ask that same on-device model to describe the picture.

The app runs in Apple's app sandbox (a security enclosure for apps) with access only to the folder you choose, remembered with a security bookmark that macOS provides. It has no network permission, so your screenshots, the text read from them and the titles cannot leave your Mac through the app. The image itself is never modified; only the file name changes.

What stays on your Mac, and for how long

To let you undo and correct renames, the app keeps a few small files inside its own container on your Mac. We never receive them:

• Settings: the watched folder (and its bookmark), the languages and your choices for the optional features. They stay while the app is installed.
• History of renames (log.tsv): dates and times, original and new file locations, titles and the result. If a screenshot is left unchanged because it looked sensitive, only a category is noted (“possible login details”, “possible bank details” or “possible card, account or long code number”), never the word or the number. Kept for up to 30 days and at most 1,000 lines; after that you can no longer undo from the app (the screenshot itself stays where it is).
• Timing record: how long reading and titling took, whether it was the first screenshot after opening the app, how many characters were read and the load on your Mac. No file locations, names or titles. Kept for up to 14 days and at most 300 lines.
• Your corrections and the titles you rejected, so the app avoids suggesting them again. The last 200 lines of each file are kept, and only the 6 most recent styles are used to imitate your style.

The app does not copy or store the content of your screenshots. While it is open, it notes in memory which app was in front when each screenshot was taken; this is never saved or sent, and it is used only if you turn on Add App Name to Title.

All of this lives in the app's container. To remove it, move the app to the Trash and then, in Finder, choose Go → Go to Folder…, type ~/Library/Containers and move the folder com.shiftcommand4.ShiftCommand4 to the Trash. File names and Finder comments already written to your screenshots stay with those files.

Optional features (off by default)

• Save Text in Finder Comment: saves the text read in each new screenshot in that file's Finder comment, on your Mac, so Spotlight can search it. It is never saved for screenshots that look sensitive, and it never overwrites a comment you wrote. The comment travels with the file if you copy it to another Mac or disk, and is deleted with the file.
• Open at Login: opens the app when you sign in to your Mac.
• Add App Name to Title: the name of the app in front becomes part of the file name.

Screenshots that look sensitive

By default, ShiftCommand4 titles all your new screenshots, including those that show login details or card or bank numbers. The AI is told not to include passwords, keys or card or bank numbers in a title, and the app also rejects titles with long numbers. We try to keep those details out of the title, but we can't guarantee it: the AI can make mistakes, a short password could end up in the name, and context such as the name of a service can appear. If you prefer those screenshots to keep their original name, turn on Skip Screenshots with Sensitive Data in the menu (it is off by default). This is a simple check that runs only on your Mac and can't catch everything. Whether the option is on or off, the text of a screenshot that looks sensitive is never saved in the Finder comment.

Apple's technology and purchases

The app relies on features built into macOS, such as Apple Vision and Apple Intelligence, which are provided and governed by Apple. Purchases go through the Mac App Store, so Apple handles payment and we don't see your payment details. The Privacy Policy… item in the app's menu opens this page in your web browser: that is your browser connecting to this website, not the app.

Part 2 — This website

This website is static. It does not use cookies, analytics, advertising or third-party scripts, fonts or trackers, so there is no cookie banner. Like any website, the hosting provider that delivers the pages may keep standard technical logs (for example your IP address, the page requested and the time) for security and reliability. We don't use them to identify or track you.

Part 3 — If you contact us

If you email us for support, we receive your email address and your message. We use them only to reply and to solve your query, and we don't share them. We keep them for as long as we may need them to follow up on your query, and you can ask us to delete them at any time. Please don't send screenshots that contain personal information.

Your rights

These rights apply to the personal data we may actually hold: your support emails and the technical logs of the website. The app sends nothing to the developer, so there is nothing from the app to access or delete.

You can ask for access, rectification, erasure, restriction of processing, objection and portability, by writing to support@shiftcommand4.com. If you think your data is not being handled properly, you can complain to the Spanish data protection authority (AEPD, aepd.es).

Children

ShiftCommand4 doesn't collect personal data from anyone, including children.

Changes

If this policy changes, we'll update the date above.
