About Deeds

Securing Our Ummah's Digital Dignity

Deeds is the parent company of The Masjid App. See more at thedeeds.net.

In today's interconnected world, our digital and physical lives are inseparably linked. Companies routinely collect and analyze our personal data, creating real-world consequences for Muslim communities. When your online activities, location data, and communications are tracked, this information can directly impact physical safety, community surveillance, and targeted discrimination against the Ummah. Our privacy solutions protect not just your digital identity, but your actual lived experience—preventing biased algorithms from restricting your opportunities, protecting community spaces from unnecessary monitoring, and ensuring your personal data isn't used to inform policies that harm Muslims worldwide. By securing your digital footprint, you're taking a practical step to protect both yourself and the broader Ummah from very real physical threats that begin in the digital realm.

About The Masjid App

Connecting Muslim communities with their local masjids in a safe and optimized way—like never before

Masjids are the data centers of our communities. It is of the utmost importance to help Masjids protect not just their immediate community but preventing their community from being leveraged to power harm to other parts of the Ummah. For too long, Masjids have been using tools not designed for masjids—systems that aren't optimized for their unique needs and often compromise the privacy of their congregations.

Unlike big tech's biased algorithms that show communities only what generates themselves money and power, The Masjid App provides real free speech and transparent communication, making events and announcements accessible to all without manipulation.
