Data and licences
Zaad stands on generous work by others. Here is what it uses, who made it, and under which licence.
Maps and places

Mosque locations and names © OpenStreetMap contributors, available under the Open Database License. Zaad’s mosque files are a derivative database of OpenStreetMap and are themselves offered under the ODbL 1.0: see the notice and the licence. The current files include no Overture Maps data.
Map data on the mosques map is also © OpenStreetMap contributors. Pakistani city coordinates were curated from public-domain government records and OpenStreetMap.
OpenFreeMap and OpenMapTilesMap tiles
The map style and tiles come from OpenFreeMap, using the OpenMapTiles schema.
GeoNamesCC BY 4.0
World city names, coordinates, time zones and populations are derived from the GeoNames geographical database (cities15000, countryInfo and admin1CodesASCII), licensed under CC BY 4.0. Changes: reduced to the fields Zaad needs, coordinates rounded, alternate names filtered and folded to ASCII, and re-encoded. Provided “as is”, without warranty.

In Shikarpur, Zaad shows the times of the printed jantri, compiled by Hakeem Molana Muhammad Fazlullah Soomro (RA), Shikarpur, Sindh.
adhanMIT licence
Prayer times are calculated with adhan for Dart (version 2.0.0+1) by Batoul Apps and contributors, from the formulas in Jean Meeus’s Astronomical Algorithms. This website runs a JavaScript port of that same version, so its times match the app.
Hijri datesUmm al-Qura
Hijri dates follow the Umm al-Qura calendar (the hijri package in the app, your browser’s built-in calendar here), with each country’s usual offset.
