Privacy Policy

Last updated: 29 October 2026

AltShiftBase makes small, focused apps for Mac and iOS. Our approach to privacy is simple: the apps collect nothing. This policy covers every AltShiftBase app and this website.

The Apps

We don’t collect, store, or share your personal data. There are no accounts and no sign-in.
Your data stays on your device, using local files and Apple’s standard on-device storage where applicable.
Optional iCloud sync, where offered, stores data in your private iCloud container — tied to your Apple ID and not accessible to us.
No analytics, no tracking, no third-party SDKs, and no crash reports sent to any server.
Exports are yours. Any file you export (for example, CSV or PDF) is created at your request and stays under your control.

Because the apps collect nothing, there is nothing for us to sell, share, or lose.

This Website

This website uses Google Analytics to understand anonymous, aggregate traffic (such as page views). It may set cookies for this purpose. No personally identifiable information is collected, and this data is never linked to your use of any app. You can block analytics with your browser or an ad/tracker blocker.

Children’s Privacy

Our apps are safe for all ages. We do not knowingly collect any information from anyone, including children under 13 — because we don’t collect information at all.

Per-App Notes

Individual apps may include app-specific details. Where they differ, the app’s own notes apply in addition to the above.

Daily Focus — Timer sessions, tags, and preferences are stored locally (with optional private iCloud sync). CSV export is user-initiated; exported files remain under your control.
MDB File Viewer — Reads the Access databases (.mdb/.accdb) you open and writes CSV or SQLite files to the folder you choose. Everything runs on your Mac; your source files are opened read-only and never modified. Passwords you enter for encrypted databases are used only in memory to open the file — they are never stored, saved, or sent anywhere.
Page Tiles - Split & Print — Reads only the image or PDF files you choose and generates a tiled PDF in the location you select. Processing happens entirely on your Mac; files are never uploaded, and source files are not modified.
MediaProbe — Reads the video and audio files you open in order to show their metadata; your media is read, never edited. Reports you export (JSON, text, or CSV) are written where you choose. Inspection happens entirely on your Mac, and the app ships without the network entitlement, so it cannot connect anywhere — nothing to upload, and no codecs or system extensions are installed.
Longform Writer — Your projects are files on your Mac (a .longform package of plain-text Markdown files), opened and saved only where you choose. Word files you send or import, PDFs, archives and other exports are written where you choose and stay on your Mac. The app connects to the internet only when you use Look Up DOI or ISBN: it then sends that one identifier, and nothing from your writing, to Crossref (for a DOI) or Open Library (for an ISBN), with a header naming the app and our support address as those services ask. Like any website, they see the request and your IP address, and their own privacy policies apply. Nothing else is ever sent, and there is no account.

Changes

If this policy changes, we’ll update it here with a new date.
