Privacy Policy
Last updated: 2026-04-11
Who we are
QNTM is a post-quantum blockchain protocol operated by continuous.engineering (sole operator, Wyoming, USA). This policy covers qntmchain.ai and all subdomains. Contact: [email protected].
What we collect and why
Q chat conversations
When you talk to Q on this site, we store:
- Your messages and Q's replies
- Any name, email, or company you mention voluntarily
- Browser type, referring URL, timezone (from your browser)
- An anonymous session ID (randomly generated, no login required)
Why: To follow up with people who want to build on QNTM or learn more. We do not sell this data. We do not share it with third parties except our AI provider (Anthropic) to generate Q's replies.
Retention: 90 days. Deleted automatically after that.
Playground sessions
When you use the code playground at /playground, we store:
- Snapshots of your code (saved every run and every 2 minutes while editing)
- Your playground chat with Q
- Which templates you used, how many times you ran code, session duration
- The same anonymous session ID used for Q chat
Why: To understand what developers are building and where the SDK is confusing. This is product intelligence, not personal profiling. A notice is shown in the playground UI before any code runs.
What we never store: Private keys, wallet seeds, or any credentials your code generates. Generated keys are testnet-only and ephemeral by design.
Retention: 90 days.
Contact form
Name, email, company, and message. Used only to respond to your inquiry. Not shared. Retained until resolved.
Logs and infrastructure
Cloudflare processes all traffic. Standard access logs (IP, request path, timestamp) are retained per Cloudflare's default policy (typically 7 days). We do not run our own server-side analytics. We do not use Google Analytics or similar tracking tools.
Cookies
We do not set tracking or advertising cookies. Cloudflare may set functional cookies (bot protection, performance routing). No consent banner is shown because we have no analytics or ad-tech cookies. If that changes, we will add one.
Third-party processors
| Processor | Purpose | Data shared |
|---|---|---|
| Cloudflare | CDN, Pages hosting, KV storage | All traffic, stored session data |
| Anthropic | Powering Q chat and playground AI | Your messages only, not stored by Anthropic per their API terms |
| GitHub | Source code hosting, CI/CD | None from users |
Your rights
Regardless of where you are located, you can:
- Access the data we hold about your session
- Delete your session data at any time
- Correct any information you provided
- Object to our processing
To exercise any of these rights: email [email protected] with
your session ID (shown in your browser's developer tools under Local Storage key qntm_session)
or describe your conversation. We will respond within 30 days.
Children
This site is not directed at children under 13. We do not knowingly collect data from children.
Changes to this policy
If we make material changes, we will update the date at the top of this page and note the change in our changelog. Continued use of the site after changes constitutes acceptance.
