Privacy Policy

Last updated: October 2025

TL;DR - The Short Version

We collect NO data. We log NO data. We store NO unnecessary data.

Your messages are end-to-end encrypted. We cannot read them. We don't track you. We don't sell your information. We don't hand over data to third parties because we don't have any data to hand over.

1. Introduction

Welcome to 644.ro, a Matrix homeserver operated with a singular focus: your privacy. This policy explains our data practices in plain language. Spoiler alert: there's not much to explain because we don't collect data.

2. What Data We Collect

2.1 Account Data (Minimal)

When you create an account, we store only what's technically necessary for Matrix to function:

We do NOT require or collect:

2.2 Message Data

Your messages are stored according to Matrix protocol specifications:

We do NOT use your data for:

4. Data Sharing and Disclosure

4.1 With Third Parties

We share NOTHING with third parties. No advertisers, no analytics companies, no data brokers. Zero.

4.2 With Other Matrix Servers (Federation)

When you communicate with users on other Matrix servers, messages are transmitted according to the Matrix protocol. The privacy practices of other servers are beyond our control. Choose your federation connections wisely.

4.3 Legal Requests

We comply with valid legal requests under Singapore law. However, since we don't log IP addresses, timestamps, or metadata, there's very little we can provide even if compelled. We cannot decrypt end-to-end encrypted messages.

We commit to:

5. Data Security

We protect the minimal data we store through:

6. Data Retention and Deletion

You control your data:

7. Your Rights

Under various privacy laws, you may have rights including:

To exercise these rights, contact us at dnsadmin@644.ro.

8. Children's Privacy

Matrix homeservers are not specifically designed for children. We do not knowingly collect data from users under 13 (or applicable age in your jurisdiction). If you believe a child has created an account, please contact us.

9. International Data Transfers

Our server is located in Singapore. If you access 644.ro from outside Singapore, your connection data passes through international networks. However, since we don't log this data, there's minimal privacy impact.

10. Changes to This Policy

We may update this policy to reflect service changes or legal requirements. Major changes will be announced through:

Continued use after changes constitutes acceptance. We recommend reviewing this policy periodically.

11. Technical Implementation Details

For the technically curious, here's how we ensure privacy:

12. Compliance

This server operates in compliance with:

13. Contact Information

For privacy-related inquiries, concerns, or requests:

14. Philosophy

We built 644.ro on the principle that privacy is a fundamental right, not a feature. The best way to protect your data is to not collect it in the first place. We can't leak what we don't have. We can't sell what we don't collect. We can't be forced to hand over what we don't store.

In the spirit of Unix permissions, 644.ro gives the world read-only access by default. Your data is yours alone—readable and writable only by you (root).

The Bottom Line

if (weHaveYourData) { weDoNot(); }

We're here to provide infrastructure for secure communication, not to monetize your conversations or build advertising profiles. Privacy isn't our business model—it's our only model.
