Almanac Privacy Policy

Last updated: 30 August 2026

Almanac is a home-maintenance app. This page describes what it does with your data. It is short because the app does very little with it.

In one sentence

There is no Almanac server, no account, no sign-up, and the app’s own code makes no network calls. Your record stays on your phone, with one exception: Android’s automatic backup keeps an encrypted copy in your Google account so that you still have it if you change devices. It is described below, and you can turn it off.

What the app stores, and where

Everything is stored locally on your device, in two files only Almanac can read:

Data	Where
The equipment you add	local SQLite database (`almanac.db`)
Your record of work: dates, notes, costs, companies	same database
Dates you find (last service, roof age…)	same database
Your settings: theme, season, reminders, display	local preferences
How many donations you have made	local preferences, kept separate from the above

None of it is transmitted to the app’s author, or visible to them. The only copy that exists elsewhere is the Android backup described below.

Worth knowing before you need it: “Erase everything” removes this data from the device at once, with no undo. If the Android backup is on, an earlier copy may survive until the next backup replaces it. The PDF export is still the only way to keep your record in a form you control, readable without Almanac.

What leaves the device, and when

Four cases. Three are started by you; the first is not, which is why it comes first.

Android’s automatic backup. Android copies Almanac’s database and your settings to the backup storage attached to your Google account, as it does for the other apps on your phone. It is what gives you back your equipment and your record when you reinstall the app or move to a new phone.

What is worth knowing about it, precisely:

Android performs it, not Almanac. The app takes no part in it and still makes no network calls; it only declares which files are worth backing up.
It is encrypted with your device’s lock code, on Android 9 and later. Google holds the copy without being able to read it, and Almanac’s author has no access to it at all.
It is on by default, and you can turn it off. In Android’s settings, under Google then Backup, either for the whole device or for Almanac alone.
It is a deliberate choice. Almanac has no server, so the database on your phone is your record, including the work you entered for jobs done before you had the app. Without this backup, a lost phone would take with it the document you would show a buyer or an insurer. We would rather give you an encrypted copy you can refuse than a loss you could not undo.

A donation. Payment is handled by Google Play, not by Almanac. You give your payment details to Google; the app never sees them and stores nothing about them. Almanac receives only the confirmation that a purchase succeeded, and keeps only a count. What Google collects in the process is covered by Google’s privacy policy.

A Play Store review. If you use “Rate the app”, the exchange is between your device and Google Play.

A PDF export. The file is created on your device, and you then choose what to do with it through Android’s share sheet. Almanac does not send it anywhere and does not know where you send it.

Permissions, and why they exist

Honesty requires listing the ones you would see if you inspected the app:

Permission	Reason
Notifications	Due-date reminders. Deny it and the app works, without reminders.
Boot completed	Rescheduling your reminders after a restart, which would otherwise lose them.
Internet, network state	Contributed by the Google Play libraries (donations, reviews), not by Almanac’s own code.
Foreground service, wake lock	Used by reminder scheduling.

The Google Play libraries bundled in the app may send their own diagnostics to Google. Almanac does not control that behaviour and adds nothing to it: there is no analytics, no advertising tracker and no crash-reporting tool in this app.

What Almanac does not do

No ads, no ad network, no advertising ID.
No selling or sharing of data with third parties.
No account, no email address requested.
No location, no contacts, no photos, no microphone.

Children

Almanac is not directed at children and knowingly collects no data about them: it collects none, from anyone.

Your rights

Since your data lives only on your device, you control it directly: “Profile → Erase everything” removes all of it, and uninstalling the app does the same. There is nothing to request from us, because we hold nothing.

Changes

This policy will change if the app changes. The date at the top is authoritative; the full history is public in the project’s repository.
