Privacy

VMark respects your privacy. Here's exactly what happens — and what doesn't.

What VMark Sends

VMark includes an auto-update checker that periodically contacts our server to see if a new version is available. This is the only network request VMark makes.

Each check sends exactly these fields — nothing more:

Data	Example	Purpose
IP address	203.0.113.42	Inherent in any HTTP request — we can't not receive it
OS	darwin, windows, linux	To serve the correct update package
Architecture	aarch64, x86_64	To serve the correct update package
App version	0.5.10	To determine if an update is available

The full URL looks like:

https://log.vmark.app/update/latest.json?target=darwin&arch=aarch64&version=0.5.10

You can verify this yourself — it's defined in tauri.conf.json. Search for "endpoints".

What VMark Does NOT Send

• Your documents or their contents
• File names or paths
• Usage patterns or feature analytics
• Personal information of any kind
• Crash reports
• Keystroke or editing data
• Hardware identifiers or fingerprints
• Any unique install ID or tracking token

How We Use the Data

We aggregate the update check logs to produce the live statistics shown on our homepage:

Metric	How it's calculated
Unique IPs	Count of distinct IP addresses per day/week/month
Pings	Total number of update check requests
Platforms	Count of pings per OS + architecture combination
Versions	Count of pings per app version

These numbers are published openly at log.vmark.app/api/stats. Nothing is hidden.

Important caveats:

• Unique IPs undercount real users — multiple people behind the same router/VPN/corporate network count as one
• Pings overcount real users — one person may check multiple times per day
• The real number of active users is somewhere between these two numbers

Data Retention

• Logs are stored on our server in standard access log format
• Log files rotate at 1 MB and only the 3 most recent files are kept
• Logs are not shared with anyone
• There is no account system — VMark doesn't know who you are
• We do not use tracking cookies, fingerprinting, or any analytics SDK

Open Source Transparency

VMark is fully open source. You can verify everything described here:

• Update endpoint configuration: src-tauri/tauri.conf.json
• No other network calls exist in the codebase — search for fetch, http, or reqwest yourself

Disabling Update Checks

If you prefer to disable automatic update checks entirely, you can block log.vmark.app at the network level (firewall, /etc/hosts, or DNS). VMark will continue to work normally without it — you just won't receive update notifications.
