What Serial Terminal Does

Serial Terminal is a native macOS application for RS232, RS485, RS422, and TTL serial communication over USB-to-serial adapters. It sends and receives bytes in ASCII or hex, with logging and protocol analysis. It runs entirely on your Mac.

Data Collection

Serial Terminal does not collect, transmit, or store any personal data. Specifically:

• No serial data leaves your Mac. Bytes sent and received exist only in the app's memory and your local log files (if logging is enabled).
• No device information is collected. Port names, baud rates, and adapter identifiers are stored locally for your convenience and never sent anywhere.
• No usage analytics. The app does not include any analytics SDK, tracking pixels, or telemetry. We do not know how you use the app.
• No crash reporting. The app does not send crash reports automatically. If you report a bug, you choose what information to share.

Network Communication

The app makes no network connections for serial traffic — communication is over the USB-to-serial adapter you plugged in. The only network access is:

• License activation (DMG version only): If you purchased via Polar.sh, the app contacts dl-serial-terminal.voltrus.id to validate your license key. This sends only your license key and a device identifier — no other data.

The Mac App Store version does not include license activation — Apple handles everything.

Local Storage

The app stores the following data locally on your Mac:

• Port settings (baud rate, data bits, parity, stop bits) — stored in app preferences
• Macro / quick-send presets — stored in app preferences
• License activation data (DMG version only) — stored in macOS Keychain
• Session logs — only if you explicitly enable logging, written to a folder you choose

All local data can be deleted by removing the app (and deleting any log files you saved). No residual data is left on your Mac after deletion.

License Purchase

Licenses for the DMG version are processed through Polar.sh. We receive only your email address and purchase details. We do not receive or store payment card information. License keys are managed by Polar.sh.

The Mac App Store version is processed by Apple. We receive only the information Apple provides through App Store Connect (sale reports with anonymized data).

Children's Privacy

Serial Terminal is an industrial automation and engineering tool. It is not directed at children under 13. We do not knowingly collect information from children.

Cookies and Analytics

This product page (voltrus.id/serial-terminal/) uses privacy-focused analytics (One Dollar Stats) that does not use cookies or track individual users. The app itself contains zero analytics.

Third-Party Services

• Polar.sh — Payment processing and license key management (DMG version only). Their privacy policy applies to purchase data.
• Apple App Store — Payment processing and distribution (App Store version). Apple's privacy policy applies.
• Cloudflare — Hosts the license validation and update server. No personal data is stored on Cloudflare beyond temporary request logs.

Data Retention

We retain your email address (from Polar.sh purchases) for as long as necessary to provide license support. We do not maintain any database of users, devices, or usage patterns. You can request deletion of your purchase data by emailing us.

Your Rights

Depending on your jurisdiction, you may have the right to:

• Request access to the personal data we hold about you
• Request deletion of your personal data
• Object to processing of your personal data
• Request a copy of your data in a portable format

Changes to This Policy

We may update this policy from time to time. Changes will be posted on this page with an updated revision date. Continued use of the app after changes constitutes acceptance.
