Privacy Policy

Effective date: June 30, 2026

Bit Alchemist (“Bit Alchemist”, “the app”, “we”) is a programmer's calculator for iPhone and iPad. We built it to respect your privacy completely: the app collects no personal information, requires no account, and works fully offline. This policy explains what that means and the one place data is handled — the optional feedback form on this website.

In short: the app has no servers, no analytics, no ads, and no third-party SDKs. Nothing you calculate ever leaves your device.

Information the app collects

None. Bit Alchemist does not collect, transmit, or share any personal information. It does not require an account or sign-in, contains no advertising or analytics, and makes no network connections to operate. Your calculations, history, registers, and settings stay on your device.

Information stored on your device

So the app remembers your work between launches, it stores the following locally on your device only, using Apple's standard on-device storage:

Settings — your chosen base, word size, signedness, display preferences, and which CPU flags are shown.
Register bank — the values and optional labels you save to R0–R7 / memory.
Calculation history — the results you commit, with their expression, base, word size, signedness, and flags snapshot.

This information never leaves your device, is not visible to us, and is removed when you clear it in the app or delete the app. If you use iCloud device backups, this data may be included in your own encrypted Apple backup under Apple's terms — we have no access to it.

No tracking

The app does not track you across other companies' apps or websites. It contains no advertising or analytics SDKs and does not use the device Advertising Identifier (IDFA).

Feedback you send us

If you contact us through the feedback form on this website, we receive the information you choose to provide — your name, email address, and message — delivered to our support mailbox by email. We use it solely to read and respond to your message. We do not sell it, use it for advertising, or share it with third parties, and we keep correspondence only as long as needed to handle your request. The feedback form is part of this website; the app itself sends nothing.

Children

The app is suitable for general audiences. Because it collects no personal information, it does not knowingly collect information from children.

Changes to this policy

We may update this policy from time to time. The effective date above reflects the most recent version.
