Your mobile privacy isn’t a lost cause. It’s our mission.

ChatMail paired with our custom OS, Renati, operates independently from Google, third parties and abstains from data sharing and collection. Instead, we proactively eliminate hardware and software that exposes your most confidential data. To this end, we’ve removed access to the Google Play Store, internet browsing, GPS, USB signalling, NFC, SMS, MMS, GSM calling, and Bluetooth.

Silouette with caption, ChatMail has zero tolerance for data collection.

Security-first design doesn't make compromises.

No phone number, no one is listening.


Disclosing your phone number on websites and social media networks can expose you to fraudulent activities, as it becomes effortless for malicious individuals to contact you and carry out their deceitful schemes. Apps like WhatsApp, Signal, X, and WeChat are prime examples where phone numbers aren't just an optional addition but a mandatory requirement for account creation. Hackers reach out to your mobile service provider, posing as you, and utilize the personal information they have stolen from you to bypass security verifications.

No metadata, no problem.


Metadata silently betrays your secrets divulging critical details such as who said what, who knew what, and every edit made. It hides in common applications, beyond your control.

  • Privacy-focused operating systems that allow third party apps are not foolproof and have been breached
  • Screen-watching exploits defeat encryption
  • A lost device; with the right tools, all data can be exposed
  • All keyboards send data for spell checking, suggestions, and performance metrics. They even store what you type, including passwords.
  • Command and control exploits from malicious content

No server storage, no data leaks.


In today's data-hungry mobile-first world, no individual or organization is immune to the digital collection tsunami. Personal Identifiable Information (PII) is by far the top category sought in breaches. DOB and/or SSN data are the most frequently compromised type, leading to exposure of critical accounts. Name and physical address, and personal health information are second and third.

According to Security Magazine, the cause of data breach incidents was:

  • 35% were from remote workers
  • 29% from third-party vendors
  • Over 50% through compromised accounts by responding to a direct message
  • 45% from phishing link
  • 33% say malicious actor claimed to be a customer, prospect or vendor

Our data philosophy: less is more. We don't store messages on our servers, so they can't be recalled and our system prevents storage of contacts and rosters.
