# YMRTECH

> YMRTECH is a Linux systems and cloud security engineering practice run by Yannick M. Richard, and the operator of a consumer VPN service: a WireGuard tunnel from your devices to a single gateway in a Montreal datacentre, with three DNS postures, no activity logs, and unlimited fair use.

The client-facing guides live at https://ymrtech.com/docs/. Each one is short and task-shaped; the claims behind the service are stated, with what can be checked, on the pages linked below.

## Guides

- [Choosing a tier](https://ymrtech.com/docs/tiers/): The three tiers differ in DNS only — pipe leaves your resolver alone, privacy resolves inside the tunnel, security adds ad and tracker blocking.
- [DNS ad and tracker blocking](https://ymrtech.com/docs/dns-blocking/): How the security tier's filtering resolver works — what it blocks, what DNS filtering cannot see, and why nothing about your queries is stored.
- [Requesting a whitelist entry](https://ymrtech.com/docs/whitelisting/): How to ask for a blocked domain to be allowed on the security tier — what the request becomes, what gets approved, and what stays blocked on purpose.


## Site

- [VPN service](https://ymrtech.com/vpn/): the three tiers, the price, the device count, and what the service does not do.
- [VPN technical dossier](https://ymrtech.com/vpn/technical/): who runs the tunnel, how the tiers work, what is and is not logged, and how to verify each claim.
- [What we log](https://ymrtech.com/logging/): the exact list of records, with retention.
- [Infrastructure audit](https://ymrtech.com/audit/): the signed report that tests the logging posture instead of asserting it.
- [Client portal](https://ymrtech.com/account): sign in, add a device, choose a tier, run the DNS leak test.
- [Client setup guide](https://ymrtech.com/install): WireGuard on each platform.
- [Writing](https://ymrtech.com/writing/): engineering notes, including the DNS and filtering material behind the guides.

## Optional

- [Service status](https://uptime.ymrtech.com/status/ymrtech): the live checks for the portal, both tier tunnels, both tier resolvers, the website, the forge and mail.
