1. Who publishes the app
AWAS is published by AstafLab, an independent developer. Questions about this document can be sent to contact@astaflab.com.
2. What this document covers
This document covers the AWAS Android app, package com.astaflab.awas, distributed on Google Play. Installing or using the app means accepting it.
Google Play applies its own terms to the download itself, independently of this document. Where the two disagree about that exchange, Google's prevail.
How AWAS handles data is a separate question, answered in the privacy policy. The short version is that it collects nothing.
3. Your licence to use it
You may install AWAS on the devices you use, and use it for as long as you like, personally or professionally, free of charge.
What this licence does not include: selling the app or passing it off as your own, redistributing it outside Google Play, decompiling or reverse-engineering it, or removing the notices it carries.
The one exception is the open source components described in section 6. Their own licences govern them, and those licences grant you more than this one does.
4. Prayer times, and what they are
A calculation is not a ruling. AWAS computes prayer times astronomically, from the coordinates of the place you chose and the calculation method you selected. It is a tool for computing times, not an authority on when to pray.
Different methods give different answers, legitimately, and a mosque may follow a convention or a local practice that no method reproduces. Where AWAS and your mosque disagree, your mosque is right. The app provides per-prayer minute corrections precisely so it can be brought into line with the mosque you follow.
At high latitudes there are days when the sun never reaches the required depression at all. AWAS says so rather than inventing a time, because a time produced by convention is a convention, and choosing which one is a matter for your mosque and not for a program.
Use AWAS as an aid. Do not rely on it as your sole authority for religious observance.
5. Alerts
Prayer alerts are a convenience, and they depend on your device. Android may delay an alert to save battery, and it may drop one entirely if the app is force-stopped, if its permissions are withdrawn, or if the system is under pressure. The app tells you when it can only schedule inexactly, and how to change that, but the timing is finally Android's decision rather than the app's.
Do not treat a missing or late alert as evidence that a prayer time has not arrived.
6. Who owns what
AWAS — its source code, its interface, its design and the AWAS and AstafLab names — belongs to AstafLab. Nothing here transfers any of that to you. Using the app grants you the licence in section 3, and nothing more.
The app also bundles open source components, and those are not AstafLab's to claim: an astronomical engine, a Python runtime and its libraries, the Flutter framework, two typefaces under the SIL Open Font License, and a city database derived from GeoNames under CC BY 4.0. Each keeps its own licence, and each licence text ships with the app. Read them under Settings → About → Open source licences.
7. No warranty
AWAS is provided as it is, without warranty of any kind. AstafLab does not guarantee that it is free of defects, that it will suit any particular purpose, or that it will run on every device.
To the extent the law allows, AstafLab is not liable for loss arising from use of the app, including a prayer observed at the wrong time. Where the law does not allow a limitation, it does not apply to you.
Nothing in this section limits your rights under any consumer protection law that applies to you.
8. Changes
These terms may change when the app does. Any changed version is published on this page, with its effective date, before the release it describes. Continuing to use the app after that date means accepting the new version.
AWAS is free of charge and contains no purchase, no subscription and no advertising. Should that ever change, the terms will say so here before it ships, and the change will apply only to what comes after it.
