Short version: Tierux is a developer tool. We collect only what is necessary to operate the service. We do not sell your data. Your Google Play purchase data is processed on your own infrastructure.
Tierux is operated by Marios Tsigkas, of Parren, 11525, Athens, Greece ("we", "us", "our"). We are the data controller responsible for determining the purposes and means of the processing of personal data described in this Privacy Policy.
This Privacy Policy explains how we collect, use, and protect information when you use our MCP server, SDK, and associated web tools (collectively, "the Service").
For privacy-related questions, contact us at contact@tierux.com.
We collect the following categories of information:
| Category | Examples | Purpose |
|---|---|---|
| Account data | Email address, organisation name | Account creation and communication |
| Configuration data | Project IDs, product mappings, paywall configs | Running the Service on your behalf |
| Usage data | API call counts, error rates, latency metrics | Service reliability and improvement |
| Technical data | IP addresses, user-agent strings, request timestamps | Security, rate limiting, abuse prevention |
We do not store Google Play purchase tokens or transaction details. Purchase verification requests are proxied to Google's API and the result is returned to your application; we do not persist the raw purchase data.
We use the information we collect to:
We do not use your data for advertising or sell it to third parties.
We share data only in these circumstances:
We retain data for as long as your account is active or as needed to provide the Service. Configuration data is deleted within 30 days of account closure. Aggregated, anonymised usage statistics may be retained indefinitely.
Server logs containing IP addresses and request metadata are retained for up to 90 days for security purposes.
We implement industry-standard security measures including:
No method of transmission or storage is 100% secure. We encourage you to protect your own API keys and service account credentials.

The Service's web interface uses functional storage necessary for authentication and session management. We also use Google Analytics 4 to measure aggregate traffic — but only after you explicitly accept analytics cookies via the consent banner shown on your first visit. Until you accept, no analytics cookie is set and the Google Analytics script is never loaded. You can change your cookie preferences at any time: choose Decline on the banner, or clear the stored choice (remove the tierux_consent entry in your browser's local storage) to show the banner again and switch your answer.
The Service is intended for developers and is not directed at children under 16. We do not knowingly collect personal data from children. If you believe we have inadvertently collected such data, contact us and we will delete it promptly.
The Service is hosted on Google Cloud infrastructure. Data may be processed outside your country of residence. Where required, we rely on Standard Contractual Clauses or other lawful transfer mechanisms to ensure adequate data protection.
We may update this Privacy Policy from time to time. We will update the "Last updated" date at the top and, for material changes, notify you by email or via a notice in the Service. Continued use of the Service after changes constitutes your acceptance of the updated policy.
