Privacy Policy
Almanac · Last updated 22 August 2026
Almanac has no accounts, no sign-in, and no server of its own. It shows no ads and contains no advertising or behavioural-analytics software. Almost everything it knows stays on your device — and what does leave it is listed below, in full.
This policy explains the little that does leave your device, and why.
What stays on your device
Almanac keeps a small private database inside the app’s own storage. It holds:
- A random identifier created the first time you open the app. It is used only to pick which passage you see, so that two people on the same day in the same weather do not always get the same one. It is not tied to you, your device, or any account, and it is never sent anywhere.
- The passages you have read, with the date, the time of day, and the approximate location they were chosen for.
- Your most recent location, rounded to about 1.1 km before it is written down. Almanac never stores a more precise position than that, even when the operating system offers one.
- A cache of recent weather and sunrise times, kept for about a day and then deleted.
- Which passage collections you own.
The passages themselves ship inside the app, so passages you have already opened stay readable offline. Choosing a new one needs a weather lookup.
On Android, this database may be included in your device’s automatic backup to your own Google account, if you have that turned on. This is what lets your reading history follow you to a new phone. It goes to your own account, not to us — we have no way to read it. You can turn it off in your Android backup settings. iOS backups behave the same way.
What leaves your device
| Sent to | What | Why |
|---|---|---|
| MET Norway api.met.no |
Coordinates rounded to about 1.1 km, your IP address, and basic request information | To look up the current weather, which decides the passage |
| RevenueCat | A randomly generated App User ID and limited technical information — platform, OS version, and the time of the request | Every time the app opens, to fetch what is for sale and whether you already own it |
| RevenueCat, and Apple or Google | Purchase history, and an Apple receipt or Google purchase token | Only if you buy or restore a purchase |
Your exact location is never sent, and never stored. Coordinates are rounded before they are written down or transmitted, because the weather does not change over a city block and the app has no reason to know where you are more precisely than that. Your IP address does reach MET Norway, as it does any website you visit; MET states that it keeps such logs for up to 90 days.
MET Norway is the Norwegian Meteorological Institute. Weather data is used under CC BY 4.0. See their privacy information.
Purchases are handled by the App Store or Google Play; Almanac never sees your payment details. Purchase state is managed through RevenueCat. RevenueCat generates its own random identifier — it does not receive your name, email, or Apple or Google account. Note that the app contacts RevenueCat every time it opens, not only when you buy something, because it has to know which collections you already own before it can choose a passage.
Location is optional
You can decline the location permission and use Almanac fully. If you do, choose a city in the app instead and the weather is looked up for that city. You can change or revoke the permission at any time in your device settings.
What Almanac does not do
- No advertising, and no advertising identifiers.
- No advertising or behavioural-analytics SDKs, and no crash reporting.
- No profiles, and no behavioural targeting.
- Almanac does not sell your personal data, and does not share it for advertising or behavioural targeting. Data goes only to the service providers named above, and only for the purposes named above.
- No accounts, and no email address is ever asked for.
RevenueCat does perform purchase analytics on the data it receives. The app stores may also collect their own diagnostics as part of distribution and payment. Those are governed by Apple’s, Google’s, and RevenueCat’s policies, not this one.
Children
Almanac is not directed at children, has no accounts, and asks for no personal details.
Keeping and deleting your data
Deleting the app removes everything Almanac stored on that device. Some things live elsewhere and are not removed by deleting the app:
- Your own device backup, if you have Android or iOS backup enabled. Clear it from your Google or Apple account settings.
- RevenueCat’s record of the anonymous customer and its purchases. Write to us and we will delete it.
- Apple’s or Google’s record of the transaction, which they keep for their own accounting and refund purposes.
- MET Norway’s server logs, kept for up to 90 days.
Purchases themselves are held by the App Store or Google Play and can be restored from the app if you reinstall.
