Techion DNS is a client for one or more Technitium DNS Servers that you control. Core server traffic travels directly between your device and that server.
This summary is provided for convenience. The full Privacy Policy below controls and explains the details, choices, retention, disclosures, and rights that apply.
This Privacy Policy explains how Techion LLC ("Techion," "we," "us," or "our") collects, uses, discloses, and retains information when you use the Techion iOS application, techion.dev, and related pages or services (collectively, the "Services").
Techion LLC is responsible for personal information that Techion determines how and why to process, including information processed through the Techion website. The operator of your Technitium DNS Server, your DNS providers, Apple, and other third parties are separately responsible for information they process under their own terms and privacy practices.
This Policy does not govern a Technitium DNS Server merely because you access it through Techion. If you use Techion for an employer, customer, or other organization, that organization may control the server data you access and may have its own privacy obligations.
The app processes information you provide or request in order to connect to and administer your configured server. Depending on the features you use, this may include:
Information needed to administer your server is processed on your device and sent directly to the server address you configure. The app does not upload your DNS queries, server content or configuration, server connection details, credentials, searches, preferences, or backup contents to Techion-operated servers.
Credentials and authentication tokens are kept in protected device storage. Saved-server records, preferences, and other app state are stored locally. Some protected credentials or cloud-stored files may remain after the app is removed unless they are separately deleted.
Your server is your responsibility. Techion does not control your Technitium server, its hosting provider, its upstream DNS services, or their logging and retention practices. If you permit insecure TLS or use an unencrypted connection, information may be exposed in transit.
Backups. If you create a backup, Techion downloads selected Technitium server data to your device. A backup may contain sensitive server content or configuration, logs, statistics, authentication information, or other content you select. Backups are stored in local app storage or, if you choose iCloud, in Techion's iCloud storage. Apple processes iCloud-stored files under your Apple account and its own terms.
Purchases. Techion PRO purchases and subscriptions are processed by Apple. The app receives product, transaction, entitlement, and subscription-status information from Apple on your device to provide and restore purchased features. The app does not upload this information to Techion-operated servers. Techion does not receive your full payment-card or bank-account details. Apple controls billing, payment processing, refunds, and related records under its own terms and privacy policy.
Diagnostics. Apple may collect and make crash or diagnostic information available to developers according to your device, privacy, and App Store settings. If Techion receives such a report, it may be used to diagnose defects, improve reliability, and provide support.
Remote update notifications. If you opt in, the app sends Techion an Apple Push Notification service (APNs) device token. Techion stores and uses this token only to send update notifications through Apple. The token identifies this app installation for notification delivery and does not give Techion access to your DNS queries, server content, or credentials. Apple processes notification delivery under its own privacy practices.
As with ordinary internet requests, Techion's hosting and network providers may process connection information, such as an IP address, when the app contacts the notification service to register or remove its token.
When you visit a Techion website, the hosting or content-delivery provider may process ordinary technical information needed to deliver and secure the site, including connection, browser, device, and request information. Techion pages may request font files from Google Fonts, which causes your browser to connect to Google and disclose ordinary request metadata to Google.
The current public policy, terms, and main information pages do not intentionally place advertising cookies or use advertising trackers. A browser, network provider, hosting provider, or linked third-party site may operate under separate settings and policies.
Techion uses information as reasonably necessary to:
Depending on the jurisdiction and context, our legal basis may be performance of a contract, your consent, compliance with a legal obligation, or Techion's legitimate interests in operating, securing, and improving the Services. Where processing is based on consent, you may withdraw consent at any time without affecting processing that occurred before withdrawal.
Techion does not sell personal information, share it for cross-context behavioral advertising, or use it to serve targeted advertisements. We may disclose information in the following limited circumstances:
Techion may also disclose information at your direction or with your consent.
Local app data. Server records, preferences, cached data, backups, credentials, and iCloud files remain until removed by you, the app, or Apple. Logging out, resetting app data, and deleting the app have different effects; protected credentials and iCloud files may remain.
Notification tokens. Techion retains your APNs device token while you are opted in to remote update notifications and deletes the stored token when you opt out.
Other records. Support, transaction, legal, security, and website records are retained only as reasonably necessary for their purposes, legal obligations, disputes, and applicable limitation periods.
Depending on where you live, you may have rights to request access, correction, deletion, restriction, objection, portability, withdrawal of consent, or an appeal of a privacy decision, and to receive equal service without unlawful discrimination. These rights may be subject to exceptions.
Techion uses reasonable technical and organizational measures designed to protect information within its control. Credentials are kept in protected device storage.
No storage or transmission system is completely secure. You are responsible for securing your device, Apple account, server, credentials, backups, and network configuration. Techion cannot guarantee the security of a server or connection you configure, particularly if you permit insecure TLS or an unencrypted endpoint.
Techion and its service providers may process information in the United States and other countries where they operate. Those countries may have privacy laws different from the laws where you live. Where applicable law requires a transfer mechanism or safeguard, Techion will rely on an available lawful mechanism. Information you direct to your configured server is transferred to the location of that server and its providers.
The Services are intended for people capable of administering a DNS server and are not directed to children under 13. Techion does not knowingly collect personal information from children under 13. If you believe a child has provided personal information to Techion, use an official support channel so the matter can be reviewed and addressed as required by law.
Techion may update this Privacy Policy to reflect changes to the Services, data practices, providers, or law. The revised Policy will identify its "Last updated" date. When required by law, Techion will provide additional notice or obtain consent before a material change takes effect. Your continued use of the Services after an effective change is subject to the revised Policy, except where applicable law requires another form of acceptance.
For privacy questions, requests, or complaints, contact Techion LLC using the official contact information provided within the app or on Techion's App Store listing. This method is used so current contact information remains available without publishing direct LLC address information on this page.
