Privacy policy
Last updated: 6 November 2026, for version 1.0.0
Arihna (formerly Sakinah) is an app for Muslims looking after their hearts: prayer times, the Qurʼān, ḥadīth, remembrance, breathing, sleep sounds and a private record of how you are. It is run by Abdul Rahim, a sole trader in England ("we"). You can reach us at support@arihna.app, and about your data at privacy@arihna.app.
The short version
- There is no account. Nothing you write, feel or record is sent to us (your phone's own backup aside, below).
- We don't sell anything about you, show advertising, or use advertising IDs.
- A few things do leave your phone, each listed below with who receives it and why.
What stays on your phone
Your journal and reflections, your feelings and check-ins, your answers to the wellbeing check, your prayer record, the āyāt and ḥadīth you save, your notes and tasbīḥ counts, your place and its coordinates, your masjids, walks and footsteps, your reminders and Fajr alarm, and the look you choose.
Prayer times and the qiblah are worked out on your phone from your location; your location is not sent to us. The one time it leaves your phone is when you save a masjid where you are standing on the masjid walk: your phone's own map service (Apple's on iPhone, Google's on Android) is asked for that spot's street. Reminders and the Fajr alarm are notifications your phone schedules itself.
Speaking in Say it (Arihna+) is turned into words on your phone, by its own speech recognition (on Android, from Android 13) or, on a phone that has none, by a speech model Arihna keeps on your phone; nothing you say is sent, to us or to anyone. If your phone's own recognition doesn't yet have the words for your language, Arihna asks Android to fetch them from Google; nothing you say goes with that request. Arihna's own model (about 60 MB) is downloaded once, only if you ask, from Hugging Face, which sees your IP address and the download, never anything you say. What you say is held in a file on your phone only until its words are read, then deleted, unless you choose to keep your voice: then the recording stays on your phone with its entry, out of your phone's cloud backup, is never sent or exported, and is deleted with the entry or with delete everything.
Reciting aloud to the Qurʼān or to a ḥadīth you are memorising, so the page follows you, is heard by a recitation model Arihna keeps on your phone. What you recite is held in your phone's memory, eight seconds at most, never written to a file, and never sent, to us or to anyone. That model (about 36 MB) is downloaded once, only if you ask, from Hugging Face, which sees your IP address and the download, never anything you recite. The lock, if you turn it on, uses your phone's own face or fingerprint check; Arihna never sees it.
Prayer lock (Arihna+, on Android) uses usage access, only if you turn it on, to read which app is in front while a lock is on (at the prayers you choose, during a focus session, or in a quiet time you set), so it can pause the apps you chose, and, if you ask to be told before a prayer, in the five minutes before it, to name the app that will pause. On its page it reads yesterday's time in apps and unlocks, and each app's time this week. This is read on your phone when needed and is never kept or sent. Kept on your phone with your other choices: the apps you choose, and how many minutes each prayer's lock ran, for the week's line on its page.
These leave your phone only when you make a copy on purpose (Settings, Export), or in your phone's own backup if your phone backs up apps (iCloud on iPhone, Google on Android). Your journal and reflections, your feelings and check-ins, your answers to the wellbeing check, and the Library's writing, night plan and choices are kept out of that backup. What you wrote in the earlier app (version 2, before the update of late October 2026) is different: it stays where that app kept it, goes into your phone's backup as it always did, and is included when you export. Deleting everything in Settings removes them from the phone. Deleting the app removes it from this phone; if your phone backs up, its last backup can bring it back when Arihna is installed again, until that backup is replaced. To clear it too, delete everything in Arihna first and let your phone back up.
Nothing about opening Find support, or reaching it from another page, is counted or sent.
If you ever note a rest from prayer in Arihna, that note stays on your phone: it is never counted or sent, and it joins a sync or a copy only if you choose that yourself, with its own yes.
What leaves your phone
Checking for a fix. Each time Arihna opens, it asks Expo's update service (EAS Update) whether a fix is waiting. This sends your platform, the app's version and update channel, a random ID made only for updates, and your IP address. It lets us mend a broken screen without waiting for the store.
Arihna+. Each time Arihna opens, and when you buy, restore or change a plan, it asks RevenueCat whether you have Arihna+. RevenueCat checks with Apple's App Store or Google Play. This sends a random ID made only for purchases, your purchase records from the store, the app's version, your platform and your IP address. No name, no email and nothing you've written. Payment itself is handled entirely by Apple or Google; we never see your card or bank details.
Reading the Qurʼān. The Qurʼān comes from Quran Foundation's APIs through our own server at arihna.app (run on Cloudflare), which holds the credentials and keeps no record of requests. Over Wi-Fi, or when you choose download in the Qurʼān's settings, your phone downloads the Qurʼān's text, the Saheeh International translation and English word by word through Quran Foundation's Content Sync and keeps them, so you can read without a connection. Each time you open the app online (at most every six hours) it checks for Quran Foundation's updates and corrections; if a week has passed without a check, an update that needs a fresh copy may download over mobile data too. Until that copy is on your phone, a sūrah, page or footnote you open is fetched the same way and held only while the app is open; tafsir, recitations' timings, the sūrah names in English and the lists of translations, reciters and tafsirs are always fetched that way. These requests carry which content is asked for and your IP address, and nothing about you or what you read. The Qurʼān's typefaces come from Quran Foundation's font server, which sees your IP address, and are kept on your phone. What you read, save or note stays on your phone, and no personal data comes to us or to the app from Quran Foundation, which also runs Quran.com and QuranReflect; Arihna doesn't sign you in to either. This App is an independent product and is not an official application of the Quran Foundation.
Listening to a recitation. Pressing play streams the recording from Quran Foundation's audio host, which sees which recording it is and your IP address.
Finding a masjid. On the masjid walk, what you type in the search goes to OpenStreetMap's search (Photon, run by komoot in Germany) and to your phone's own map search (Apple's on iPhone, Google's on Android), each under its own privacy terms, with your IP address. Where you are is not sent with it. We receive nothing.
Your masjid's own times. If you give your masjid's website, Arihna reads its timetable from that site about once a day. The site sees your phone's IP address, never where you are.
Weather, in the earlier app only. If your phone still runs the earlier app (version 2, before the update of late October 2026) and you turned its weather on, that app sends your location, rounded to about 10 km, to our server, which asks MET Norway for the forecast and keeps no record of the request. MET Norway sees our server, never your phone. Arihna has no weather and sends no location for it.
Crash reports, only if you turn them on. They're off until you turn them on in Settings ("crash reports"). When a page in Arihna stops working, or an error closes Arihna, it then sends PostHog, in the EU, the kind of error, where in Arihna's code it happened, which kind of screen it was on, the app's version and the update it runs (the same for everyone on that update), your phone's model and system, and your IP address. No statistics ID, nothing that links one report to another, and never anything you've written. A page that stops working in Find support, Say it, your own writing or answers, or a purchase sends no report at all, and once one of those pages has been open, an error that closes Arihna sends nothing until Arihna next opens.
Help improve Arihna, only if you say yes. It's off until you turn it on in Settings ("help improve arihna"). With your yes, Arihna sends PostHog, in the EU, the screens you open in order, named by their kind and never by what they hold (the Qurʼān's chapter screen, not which chapter), a few moments finished (a breath, a round of tasbīḥ, a chapter of adhkār, a sound played to its end, reminders turned on), when the app is installed, opened, updated or put away, a random statistics ID made on your phone, an ID for each time you use the app, the app's version, your phone's model and system, and your IP address. Your use of prayer times, the Qurʼān, ḥadīth or dhikr is part of it, and that can say something about your faith, which is why it needs your yes. Never sent: your writing, feelings or answers, your location, what you paid, your taps, or whether you opened Find support. Turn it off in Settings at any time.
Links and support. Opening a link takes you to that site; writing to us opens your email app. Calls and texts from Find support are made by your phone; Arihna doesn't see or keep them.
What we never do
We don't sell or share your data, run advertising, use advertising IDs, record your screen or taps, track whether you opened Find support, or send anything you've written.
Who receives data, and where
| Who | What for | Where |
|---|---|---|
| Expo (650 Industries, Inc.) | The update check | United States |

| Hugging Face, Inc. | The speech model for Say it, downloaded once, only if you ask on a phone with no speech recognition of its own; the recitation model, downloaded once, only if you ask to recite aloud | United States |
| Cloudflare, Inc. | Runs our server, which brings you the Qurʼān, and the weather in the earlier app (no request record is kept) | Its global network |

| Your masjid's own website | Its timetable, if you give its address | Wherever that site is run |
Where data goes outside the UK or the European Economic Area, it is protected by the providers' own safeguards, such as standard contractual clauses.
How long it is kept
What stays on your phone is kept until you delete it or delete the app. RevenueCat keeps purchase records for as long as a subscription needs them and the law requires. Expo keeps update logs under its own retention policy. What you send with your yes, and crash reports, are kept by PostHog only as long as they help us improve Arihna, and deleted when you ask.
Your rights
Under UK and EU data protection law you can ask what we hold about you, have it corrected or deleted, object, or ask for a copy. We hold almost nothing ourselves; for your purchase records with RevenueCat, write to privacy@arihna.app and we'll ask for them to be deleted. If you said yes to helping improve Arihna, Settings' "ask us to delete what's been sent" writes us an email carrying your statistics ID, and we delete what was sent with it. You can complain to the Information Commissioner's Office (ico.org.uk) or your own country's authority.
Our legal basis is legitimate interests: to provide the app, keep it working, and know whether you have Arihna+. Helping improve Arihna and crash reports rest on your consent, which you can withdraw in Settings at any time.
Children
Arihna isn't made for children under 13. It collects nothing that would identify anyone, at any age.
Changes
If what leaves your phone changes, this page changes first, and the app tells you before anything new is sent.
