What this notice covers

This privacy notice covers the Pillars App v1.x only.

Future versions of the Pillars App may involve changes to data handling policy. This will require you to review and agree to a new privacy policy covering the new changes and/or features.

We don't collect location or personal* data

We believe all users of the app (both Muslims and non-Muslims) are entitled to their privacy and have built Pillars around this central principle.

Therefore, whilst the app requires your location data to calculate bespoke prayer times for your specific geolocation, this is all done locally (i.e. on the phone) and no data whatsoever is sent to Pillars or stored by ourselves.

No other data is collected via the app (e.g. personal information*).

*this excludes email addresses if you have signed up to our mailing list (to facilitate email updates).

Email address data

We collect the email addresses of individuals who have signed up to our mailing list, beta programme (early adopter) and premium subscription. This is necessary to enable us to be able to identify who should be given access. For email addresses we also include some basic data around your engagement with our emails. This is limited to information around whether you open our emails or not and click on links inside them.

Mobile number data (premium subscription only)

We collect the mobile numbers of individuals who have signed up to our premium subscription. This is necessary as one of the ways Apple identifies your Apple ID is via your mobile number (as well as your email).

Global transfer and processing

We do not collect any data apart from your email address. This may be stored and processed in any country where we operate, or where other companies provide services to us (e.g. Flodesk for mailing list). By signing up to our mailing list, you're agreeing to let us store it in, and transfer your email address to these countries.

Flodesk & Revue

We use Flodesk & Revue as a service provider in order to deliver email updates. The way Flodesk & Revue store and process your data is subject to their Privacy Policy ( &
