Demvio Privacy Policy

Effective date: 2026-09-14

Core principle: your recordings are processed entirely on your device and are not uploaded or collected by default.

1. What data we handle

1.1 Stored only on your device — never uploaded

  • The screen, window, or tab video you choose to record, and system audio when you choose to share it;
  • Cursor path, clicks, scroll, and text-selection position/timing captured during a recording (used for auto-zoom, click ripples, and trimming pauses);
  • Your editing projects, text captions, frame/fill settings, imported local media, and preferences.

This data is stored on your computer via browser local storage (OPFS and chrome.storage.local), and encoding is performed locally with ffmpeg.wasm / WebCodecs. We do not receive, view, or store your video or audio content. The exported GIF/MP4 is saved directly to your computer via the browser's download. Uninstalling the Extension or deleting a project inside it removes this local data.

1.2 Limited technical data sent to our server

When you export, the Extension sends over HTTPS to our server (pickaxiom.com) the export format (GIF/MP4), the features used, and a random per-recording project ID, to determine free/paid capabilities, issue the export grant, and prevent abuse. On startup it also makes one request that carries no identifier at all, only to fetch public settings such as the watermark text. Nothing else — no recording content and no personal information — is sent.

The "project ID" is a random UUID generated only for that recording. It contains no identity or device information and no browsing or recording content, and it cannot reconstruct what you recorded. The free version requires no sign-up or login, and we do not ask for your name, email, or Google account.

As with any HTTPS service, our server/hosting provider automatically keeps technical request logs (such as IP address, request time, endpoint, and User-Agent) for security, troubleshooting, and abuse prevention, purged on a rolling basis (within 30 days).

2. How we use data

  • To provide recording, editing, and export;
  • To enforce free-version export limits and the watermark and prevent abuse;
  • To keep the service secure and diagnose problems;
  • For aggregate, de-identified usage statistics (never containing video content).

We do not sell your data, use it for advertising profiling unrelated to the Extension, read password fields/form input/keystrokes in recorded pages, or collect cursor activity unless you have actively started a recording.

3. Screen and website content

During a recording you explicitly start, the Extension reads pointer interactions (mouse position, clicks, scroll, selection) on the tab you select and captures that tab/screen to power auto-zoom and cursor effects. This information stays on your device throughout. No page text, DOM content, or recording footage is transmitted to us or any third party.

4. Chrome permissions

  • tabCapture, activeTab, offscreen: capture the chosen tab/screen and process it locally, only after you choose to;
  • storage: save recordings, projects, and settings locally;
  • downloads: save the generated GIF/MP4 to your computer;
  • scripting, webNavigation: keep capture bound to the active tab during a recording.

Host permission https://pickaxiom.com/* is used only for the config and export-authorization calls in section 1.2. The current free release exposes no sign-in and accesses no third-party account.

5. Sharing and third parties

We do not sell or rent your personal data. Data is processed by infrastructure/hosting providers only as necessary to provide the service. The Extension includes no third-party advertising or tracking SDK.

6. Retention

  • Recordings, audio, cursor data, and projects: stored locally, deleted by you or on uninstall;
  • Export-authorization records: short-lived; settled/expired once export completes;
  • Server technical logs: retained on a rolling basis, within 30 days.

7. Your rights and deletion

You can delete recordings and projects inside the Extension at any time, or uninstall it to clear all local data. To request access to or deletion of server-side export-authorization records, contact us via the developer contact details on the Extension's Chrome Web Store listing, and we will respond within a reasonable period. Depending on applicable law (e.g. GDPR, CCPA), you may also have rights to access, correct, restrict processing, port, and lodge a complaint.

8. Children

The Extension is not directed to children under 13, and we do not knowingly collect children's personal data.

9. Security

Data in transit uses HTTPS; recording content never leaves your device. No method of transmission or local storage is perfectly secure, so please protect your device and exported files.

10. Changes

We may update this policy; updates are posted on this page with a revised effective date, and material changes will be noted in the Extension or on the website.

11. Contact

Contact information is available on the Extension's Chrome Web Store listing under the developer details.
