1. Who We Are

ArystoTech Software & AI Systems Ltd. ("ArystoTech," "we," "us," or "our") develops and distributes Windows desktop automation software and related products. This Privacy Policy applies to all ArystoTech software products and to this website (arystotech.com).

2. What Data We Collect

We collect the absolute minimum data necessary to operate our business. The table below summarizes our data collection across all touchpoints:

3. Desktop Software Products

All ArystoTech desktop software products — PyBatScheduler, PyPsScheduler, PyApiMonitor, and PyBackupScheduler — are designed with a zero-telemetry architecture:

• No usage tracking: The software does not record, report, or transmit what jobs, scripts, APIs, or files you configure.
• No crash reporting: Errors are written to local log files only. Nothing is sent to our servers.
• No analytics: We do not collect feature usage statistics, session data, or behavioral data.
• Offline activation: License keys are validated using HMAC-SHA256 cryptography on your local machine. No internet connection is required after purchase.
• Local storage only: All configuration data (job schedules, API endpoints, backup paths) is stored in JSON files on your local machine. We have no access to this data.

4. This Website

This website (arystotech.com) is hosted on Cloudflare Pages. When you visit the website, standard web server access logs may be generated by Cloudflare's infrastructure. These logs may include:

• IP address (may be anonymized at the edge by Cloudflare)
• Browser type and version
• Pages visited and timestamps
• HTTP referrer

This data is used solely for security monitoring, abuse prevention, and aggregate traffic analysis. We do not use tracking pixels, third-party analytics scripts, or behavioral advertising tools on this website.

5. Payment Processing

All purchases are processed by Paddle (paddle.com), our Merchant of Record. When you make a purchase:

• Your payment information (credit card details, billing address) is collected and processed entirely by Paddle. ArystoTech does not receive or store your payment card data.
• Paddle shares with us: your name, email address, order details, and license key assignment — for the purpose of fulfilling your purchase and providing support.
• Paddle's own privacy policy applies to data they collect. We encourage you to review it at paddle.com/legal/privacy.

Following a purchase, we retain your name, email address, and order reference to support license key reissuance, upgrades, and support requests.

6. Email Communications

If you contact us at admin@arystotech.com, we retain your email address and the content of your message for the purpose of responding to you and maintaining a support history. We do not subscribe you to marketing lists without your explicit consent.

7. How We Use Data

Data we collect is used solely for the following purposes:

• Fulfilling software purchases and delivering license keys;
• Responding to support requests and technical queries;
• Reissuing license keys if requested by a verified purchaser;
• Notifying purchasers of critical security updates (where email contact is available);
• Complying with applicable legal obligations.

We do not use your data for advertising, profiling, resale, or any purpose beyond the above.

8. Data Sharing

We do not sell, rent, or trade your personal data. We share data only in the following limited circumstances:

• Paddle: As our payment processor and Merchant of Record, Paddle receives purchase data as described in Section 5.
• Legal requirements: We may disclose data if required to do so by applicable law, court order, or government authority.
• Business transfers: In the event of a merger, acquisition, or sale of substantially all of our assets, user data may be transferred as part of the transaction. We will notify affected users via email or website notice.

9. Data Retention

We retain purchase records (name, email, order reference) for a minimum of seven (7) years to comply with applicable tax and accounting regulations. Support email correspondence is retained for a minimum of two (2) years. You may request deletion of your personal data at any time, subject to our legal retention obligations (see Section 10).

Depending on your jurisdiction, you may have the following rights regarding your personal data:

• Objection: Object to processing of your data in certain circumstances.

To exercise any of these rights, please contact us at admin@arystotech.com. We will respond within thirty (30) days.

11. Cookies

This website does not use tracking cookies, advertising cookies, or third-party analytics cookies. Cloudflare may set a strictly necessary session cookie for security and DDoS protection purposes. No cookie consent banner is displayed because we do not use non-essential cookies.

12. Children's Privacy

Our software products and website are not directed at children under the age of 13 (or 16 in the European Union). We do not knowingly collect personal data from children. If you believe a child has provided us with personal data, please contact us and we will delete it promptly.

13. Changes to This Policy

We may update this Privacy Policy from time to time. When we do, we will update the "Last updated" date at the top of this page. For material changes, we will notify purchasers via the email address on their account where possible. Continued use of our products or website after the effective date of the updated Policy constitutes acceptance.
