Privacy Policy
Effective date: April 30, 2026
This policy explains what information Wiremark collects, how we use it, and your rights regarding that information. We take a minimal approach: the tool is designed to work without collecting personal data.
1. Information we collect
Diagram content
All rendering happens in your browser. Your DSL code is encoded directly in the URL using client-side compression and is never transmitted to our servers. We do not store or process your diagrams.
Account information
Wiremark does not require an account. We do not ask for your name, email address, or any other personal information to use the editor.
Usage data
Like most websites, our hosting infrastructure automatically records standard web server logs when you visit. These may include your IP address, browser type, referring URL, and pages visited. Logs are retained for up to 90 days for security and operational purposes and are not used for advertising.
2. Cookies and local storage
Essential storage
The editor uses your browser's localStorage to remember your cookie consent
choice and may persist your last diagram between sessions. This data stays on your device
and is never sent to us. No cookies are set before you give consent.
Analytics cookies (optional — consent required)
If you choose to accept cookies, we use Google Analytics 4 to understand aggregate usage patterns (pages visited, features used, general geographic region). GA4 sets the following cookies:
| Cookie | Purpose | Duration |
|---|---|---|
_ga | Distinguishes unique users | 2 years |
_ga_* | Maintains session state | 2 years |
These cookies are only set after you click Accept cookies in the consent banner. If you decline, no analytics cookies are set and Google Analytics does not load. You can withdraw consent at any time by clearing your browser's local storage or cookies.
Google's data processing is governed by the Google Privacy Policy. You can opt out of Google Analytics across all sites using the Google Analytics opt-out browser add-on.
3. How we use information
We use the limited information we collect to:
- Operate, maintain, and improve the service.
- Understand which features and pages are most used (analytics, with consent only).
- Detect and prevent abuse or security incidents.
- Comply with legal obligations.
We do not sell personal data. We do not use it for advertising.
4. Legal basis for processing (GDPR)
If you are in the European Economic Area (EEA) or United Kingdom, we rely on the following legal bases:
- Consent — for analytics cookies (GA4). You may withdraw consent at any time.
- Legitimate interests — for server logs, to maintain security and prevent abuse.
5. Your rights
Depending on where you live, you may have rights to access, correct, delete, or restrict processing of your personal data, or to object to processing or request data portability. Because we collect minimal personal data and do not store your diagrams, most requests can be satisfied by clearing your browser's cookies and local storage.
To exercise any rights or submit a complaint, contact us at privacy@wiremark.dev. EEA residents may also lodge a complaint with their local supervisory authority.
6. Data transfers
If you accept analytics cookies, your usage data is processed by Google LLC in the United States. Google participates in the EU–US Data Privacy Framework.
7. Children
Wiremark is not directed at children under 13 (or 16 in the EEA). We do not knowingly collect personal information from children.
8. Changes to this policy
We may update this policy from time to time. We will post the revised policy on this page with a new effective date. Material changes will be announced on the changelog.
