Privacy Policy

tenkayro.de is a personal portfolio, project directory, and product-information website. It does not use advertising, behavioral analytics, fingerprinting, or tracking cookies. Local browser storage remembers the selected visual accent mode and the previous random color. These visual preferences stay on the device and are not transmitted to the developer.

Contact form

If you voluntarily use the contact form, the provided name, email address, optional subject, and message are sent through a Cloudflare Pages Function and forwarded to the configured delivery service so the message can be answered. Cloudflare Turnstile processes the verification token and connecting IP address to prevent abuse. The website does not use this information for advertising, profiling, or unrelated purposes.

External services and links

Some project pages use or link to external services such as Cloudflare Turnstile, UserJot, GitHub, Modrinth, YouTube, Twitch, or music platforms. Their own privacy policies apply when their content is loaded or their websites are opened.

This section applies generally to every current and future browser extension or add-on published by Tenkayro. Each add-on is limited to a narrow, clearly described user-facing purpose and requests only the permissions required to provide that purpose.

1. Data processed for add-on functionality

Depending on its stated function, an add-on may temporarily process content from a browser tab explicitly selected or used by the user. Website content can include text, images, audio, video, or hyperlinks. Access to this content does not by itself mean that the content is collected by or transmitted to the developer.

Unless an add-on's Store listing and product interface explicitly disclose otherwise, this processing takes place locally in the browser. Website content is not recorded, uploaded, sold, shared, used for advertising, or inspected by a person.

2. Local settings

Add-ons may use browser-provided local storage to remember settings required for their operation, such as feature configuration, interface preferences, language, display mode, or temporary per-tab state. These settings stay on the user's device and are removed when cleared through the browser or when the add-on is uninstalled. Temporary tab-specific entries are removed when they are no longer required.

3. Data categories

Add-ons do not intentionally collect personally identifiable information, health information, financial or payment information, authentication data, personal communications, precise location, browsing history, or interaction telemetry unless a future product genuinely requires a category for its visible primary function. In that event, the Store disclosure and this policy will be updated before the new handling begins.

4. Permissions and remote code

Permissions vary by function and may include limited browser capabilities such as access to the active tab, local storage, an offscreen document, or tab-media capture. Permissions are used only for the feature described to the user. Add-ons do not request broad host access merely for possible future features.

Executable code and required runtime assets are packaged with each currently published add-on. Current add-ons do not download or execute remote code. If a future product requires a materially different practice, its Store disclosure and this policy will be updated before release.

5. Sharing and Limited Use

Tenkayro does not sell add-on user data or transfer it to third parties for advertising, profiling, credit decisions, lending, or purposes unrelated to the add-on's stated function. Information received through browser APIs is used only to provide or improve the add-on's single purpose. This use adheres to the Chrome Web Store User Data Policy, including its Limited Use requirements.

If an individual add-on provides a more specific privacy notice, that notice adds product-specific details to this general policy without reducing the protections stated here.

Aero P2P Chat is designed from the ground up to respect your privacy. As a desktop application focused exclusively on direct peer-to-peer communication, there is no middleman server reading your messages or viewing your screen sharing data.

1. Data Collection

We do not collect, store, or transmit any personally identifiable information to our servers. Your local data remains entirely on your device.

2. Data Usage

Since we do not collect any user data, there is no data to use, share, or sell. All web traffic happens over a secure WebRTC tunnel directly between you and your peer. A PeerJS signaling service is used only to establish a connection between peers, but is not used to store chat messages or call media.

3. App Permissions

• Local Storage: saves your app settings and local chat data safely on your hard drive.
• Notifications: shows desktop notifications for messages and calls when you allow them.

Desktop applications and game modifications published by Tenkayro are built with the same data-minimization principle. Unless a product page clearly discloses otherwise, they do not collect telemetry, usage statistics, or personal data. Settings and other product-generated data remain locally on the user's device.

If a future application requires an online service or additional data to provide its main function, the relevant product information and this policy will be updated before that processing begins.
