Privacy policy
Updated 14 November 2026
This page says what data Mannalee keeps, where it is stored, who can see it and how to delete it. It covers the Mannalee app for iPhone and Android and the site manna-log.web.app. Mannalee is made by an independent developer, whose name is shown on the app’s page in the App Store and Google Play.
What is stored
- If you sign in with Google, Apple or email, your email address and the sign-in method are stored. Without an account there is no email address.
- An account number issued by Firebase Authentication. Everything else is tied to you through it.
- Your reading plan, marked chapters, reading history, notes, highlighted verses, topics, highlight colours, memory gems and settings, so that everything looks the same on all your devices.
- Where you stopped reading (book, chapter, verse and translation), so that “Keep reading” works on any device.
- The app version and the time of the last write, so the app can tell whether a newer Mannalee on another device has written your data.
All of this you enter yourself while using the app. Mannalee collects nothing in the background: no location, no list of installed apps, no contacts, no health data, no advertising identifier. The data is used for one thing only: to make the app work and to keep your progress on all your devices.
Data about your Bible reading
Your plan, chapter marks and notes say that you read the Bible. In some countries this counts as specially protected data. It is kept under your account, it is used only to run the app, it is never shared with anyone and never used for advertising, content targeting or sale.
Without an account
The “Start without an account” button on the sign-in screen creates an anonymous Firebase account with no email, name or password: only a number that your data is tied to. Simply opening the app creates no account. Until a plan is saved, nothing is stored for that account. Once a plan is saved, the same things are stored as for any account.
The anonymous account itself stays in Firebase Authentication even if no plan is ever saved; it holds no data.
Progress without an account can be saved into a Google, Apple or email account: “Save the plan to an account” on first run, or Profile → “Save progress”. The data stays the same.
An anonymous account belongs to that one phone (on the site, to that one browser). If you sign out, delete the app or clear the browser data, what was saved stays in the database but can no longer be opened or deleted. So either save your progress to an account or delete it in advance with “Delete progress from this device” (Profile → ⚙ → “Account and data”).
Where the data is stored
In Google Firebase: Authentication (sign-in), Cloud Firestore (the database) and Hosting (the site). The database is in Europe, in Frankfurt, region europe-west3. Data travels over an encrypted connection (HTTPS) and is stored encrypted on Google’s side.
Google processes this data as a service provider, on instructions from the developer of Mannalee and under the Firebase Data Processing and Security Terms (firebase.google.com/terms/data-processing-terms). Google provides your data with the same or equal protection as stated in this policy. Google has no free access to your data and does not use it for its own advertising. Apart from Firebase, the collected data is shared with no one.
Who can see the data
Inside the app your data is visible only to you. The developer of Mannalee has access to the database and looks at how people use the app, to make it better and to ask people about their experience.
- For each person the developer sees the account (email, sign-in method, when it was created and when the app was last opened), the plan and the Bible, marked chapters and how much of each book has been read, reading history, streak and reserve, reading speed, reading position and translations; how many thoughts of the day, notes, highlighted verses, topics, highlight colours and memory gems you have; settings (theme, palette), app version and the size of the data.
- Only in total, with no names, the developer sees which books and chapters people write notes in and highlight verses in, which verses are highlighted more often, which highlight colours people pick and how long notes are.
- Never does the developer see what you wrote yourself: the text of notes, topic names, your own labels (for gems, streams, your own books); nor what is inside backups (about those the developer knows only how many there are and how big they are).
Signing in with Google and Apple
Google passes on your email address. Apple passes on your address, or a private relay address if you chose “Hide My Email”. Your Google and Apple passwords are never visible to the app. When you delete your account in the iPhone app, Sign in with Apple is revoked as well. If the account is deleted another way (on the site or by email), remove Mannalee yourself in Settings → your name → Sign-In & Security → Sign in with Apple.
On your device
Interface settings (language, theme, colour), reading settings (text size, verse numbers), your reading position and changes that have not been sent yet are kept on the device itself. The app works without the internet: everything it needs for that is on the device, along with the texts of free translations you have opened or downloaded.
In the iPhone and Android app three more things are kept on the phone, and only there: reminder settings (whether they are on and at what time of day), the times when you marked chapters (the reminder hour adjusts to when you usually read), and the widget data (today’s date, chapters left, the day’s chapters, the reading week). None of this is sent to a server or to any other service. Reminders come from the phone itself; the app neither receives nor stores push tokens. Turning notifications down closes nothing in the app.
When you sign out, reminders are cancelled and the widget is cleared; when you delete your account, the reminder settings and mark times are erased from the phone.
If the account is deleted on another device or on the site, this phone learns about it when you open Mannalee on it: it then cancels reminders and clears the widget. Until then, reminders that were already scheduled may still arrive; to stop them, open the app on this phone or uninstall it.
The app puts nothing into the Android (Google) backup: its data is excluded from it. After reinstalling, or on a new phone, sign in and your progress comes back from the server. Progress without an account cannot be signed back into: save it to an account beforehand (Profile → “Save progress”).
The app carries its fonts inside it. The site loads them from Google Fonts.
Translation texts
Free translations (the Synodal text, KJV, BSB and others) are downloaded from the Mannalee website (manna-log.web.app) the first time a book is opened, and are then kept on the device: the site receives the usual technical details of the request (the IP address and which book is needed), with no account and no marks. The texts of some protected translations (NIV, NASB, AMP and others) are loaded straight from YouVersion (Life.Church) servers when a chapter is opened. YouVersion sees the technical details of the request: the IP address, the client and which chapter was opened. YouVersion handles that data under its own policy: bible.com/privacy. YouVersion receives no marks, no notes and no email address.
If a translation opens on its own site (bible.com, Bible Gateway), that site’s rules apply there.
What the app does not have
Mannalee has no advertising, no third-party analytics, no crash collectors and no trackers. The app does not record what you tap, does not follow you across other apps and websites, and does not send information about you to other services. Data is not sold, not passed to data brokers and not used for advertising or marketing. There are no purchases in the app, and it never sees payment details.
Backups
At your request a backup is saved as a file on your device. Besides that, when the data moves to a new format, the app saves one copy of the previous data in the database in case something goes wrong; it is deleted together with the account.
How long data is kept and how it is deleted
Your data is kept for as long as you use Mannalee: that is the point of the app: your reading history from past years should stay. There is no period after which it is erased by itself.
Deleting your account removes everything at once and for good: marks, reading history, notes, highlighted verses, topics, memory gems, the backup in the database and the sign-in itself. Deletion happens immediately, not by request, and cannot be undone. The developer keeps no separate copies afterwards. Backups you saved as a file stay with you on your device.
There will be one exception, once: on the eve of the day the Mannalee website closes and everyone moves to the app, the developer will save a full export of the database in case something gets lost in the move. The export is kept for no more than 30 days and then deleted; accounts deleted before it are not in it.
How to delete your data
In the app and on the site: Profile → ⚙ → “Account and data” → “Delete account”.
Without an account the last button on the same screen is “Delete progress from this device”: it removes both the data and the anonymous account itself.
You can also do it without opening the app: how to delete your account and data.
How to withdraw consent
You give consent to the storage of your data when you create an account or start without one. You can withdraw it on any day by deleting your account: no other data is left afterwards. Separately you can turn reminders off (Profile → ⚙ → “Reminder”) and remove the widget from the phone screen; the app keeps working as before.
Children
Mannalee is meant for adults and teenagers who read the Bible. The app does not ask for your age and does not knowingly collect children’s data. If it turns out that an account was created by a child below the age of consent in their country, write to us and the account and its data will be deleted.
How to get in touch
The email address for questions about data and deletion requests will be given here before the app goes to the App Store and Google Play. For now you can delete your account and all your data yourself, with the button in the app or on the site: Profile → ⚙ → “Account and data” → “Delete account”.
Changes
If this policy changes, the date at the top of the page changes, and the app tells you about important changes in “What’s new”. Earlier versions are not kept.
