Version: v1.0Last updated: September 5, 2026Applies to: “HLG to HDR Converter”
In one sentence: this tool is fully offline software — it makes no network connections and collects, transmits, or stores none of your data. It contains no advertising, analytics, or tracking of any kind.
This policy explains how “HLG to HDR Converter” (the “App”) handles information. The App is a video conversion tool that converts HLG-format video into HDR video. It has been written with reference to the EU General Data Protection Regulation (GDPR), the UK GDPR, the California Consumer Privacy Act (CCPA/CPRA), China’s Personal Information Protection Law (PIPL), Japan’s Act on the Protection of Personal Information (APPI), and other major frameworks, so that you can understand your rights no matter where you are. Because the App does not collect or process any personal data, most of the clauses below simply explain that there is nothing for us to collect.
1. Our core commitment: zero collection, zero networking
The App is designed “offline-first”: it has no networking capability and cannot send data to any server, actively or passively. In practice this means:
We do not collect, upload, sync, or cloud-back up any of your videos, files, or personal data;
We cannot view the content you convert, and there is no “remote diagnostics” mechanism;
The App contains no third-party SDKs, ads, analytics, crash reporting, or telemetry components.
Under the “data minimization” principle of the GDPR (Article 5) and similar rules elsewhere, processing should be limited to what is necessary. The App’s function — local video conversion — works without any personal data at all, so we collect nothing. If a future version ever needs network access or data collection, we will update this policy first and, where the law requires, obtain your separate consent.
2. What we explicitly do not collect
The App collects none of the following:
No accounts, no registration — we do not collect names, nicknames, email addresses, or other identifiers;
No content — we never collect the videos, images, or files you import or export; conversion happens only on your own device;
No device information such as hardware model, OS version, or system configuration;
No usage data such as habits, feature frequency, or operation logs;
No IP addresses or network identifiers, and no network requests of any kind;
No advertising SDKs, analytics SDKs, crash reporting, hot updates, or remote code;
We do not read your contacts, location, clipboard, or photo library (a file reaches the App only when you actively choose it in the system file picker);
No cross-site or cross-device tracking, no profiling, no personalized advertising;
No cookies or similar tracking technologies (the App is a local program; there is no web tracking at all).
Note: if you download the App through an app store (e.g., the Apple App Store), the store operator handles download and account information under its own privacy policy. That is outside our control — please refer to the store platform’s policy.
3. Where your videos are processed
All conversion takes place entirely on your device: the App reads a source file you have chosen, processes it in device memory and a local temporary directory, and writes the output file where you specify;
Temporary files created by the App are cleaned up when a task finishes or the App exits (subject to how your operating system manages its temporary directory);
Source files and output files always remain on your device or your chosen local storage — they never traverse a network.
4. Handling of your inquiry emails
We do not collect your email address. Only if you voluntarily contact us at webtoart+privacy@gmail.com will we receive your address and the content of your message, which we use solely to reply to you.
Purpose and legal basis: responding to your inquiry — based on your consent in initiating contact and our legitimate interest in handling inquiries;
Retention: emails are deleted within a reasonable period after your matter is resolved; if you ask us to delete them sooner, we will;
Third-party service: email is received and stored by the third-party provider of our mailbox (Google, i.e. Gmail), whose own privacy policy applies;
Please note: do not include sensitive personal data (government IDs, health or financial information) in emails to us.
5. About this policy page
This page is a static web page: no cookies, no analytics, no advertising, no third-party scripts, and no external fonts, images, or APIs are loaded;
Your language preference (top-right switch) is stored only in your browser’s localStorage — local storage, never transmitted or shared across sites;
The server provider hosting this page may generate standard access logs (typically including IP address, browser type, and time of access) to keep the site running and secure. We do not use them to identify you, build profiles, track you across sites, or for any marketing purpose.
6. Your rights (EU / California / China / Japan / elsewhere)
Because we do not collect or hold any personal data, the rights below are, in your case, “satisfied without needing to be exercised.” We list them honestly so you can map them against the laws that apply to you:
EU / UK (GDPR / UK GDPR, Articles 13–22): rights of access, rectification, erasure, restriction of processing, data portability, objection, and withdrawal of consent, plus the right to lodge a complaint with your local data protection authority. We also perform no automated decision-making or profiling;
California (CCPA/CPRA): the right to know, delete, and correct personal information, and the right to opt out of the “sale” or “sharing” of personal information — we do not sell, share, or collect sensitive personal information, and we do not engage in cross-context behavioral advertising;
China (PIPL): rights to access, copy, correct, supplement, and delete personal information, to withdraw consent, and to request an explanation of processing rules;
Japan (APPI): rights to request notification of purposes of use, disclosure, correction, suspension of use, and cessation of provision to third parties — we hold no personal data and provide nothing to any third party.
If you wish to raise anything above, contact us anytime at webtoart+privacy@gmail.com; we will respond within the period required by law. If the law of your jurisdiction (e.g., Brazil’s LGPD, Korea’s PIPA) grants additional rights, they are likewise satisfied because we process no personal data at all.
7. Children’s privacy
The App is not directed at children and we do not collect information from users of any age (including children under 13 or under 16). If we ever unintentionally receive a child’s information, please contact us and we will delete it.
8. Data security and retention
No cloud storage: we operate no servers, and there is no data of yours to store or lose;
Local security: the safety of your device and files depends on your operating system and storage environment — we recommend enabling OS-level encryption and a screen lock;
Retention: we retain nothing. Temporary files from conversion are cleaned up when the task ends or the App exits. When you no longer need the results, please delete the source and output files yourself;
Security incidents: because there is no centralized store of personal data, a conventional “data breach” does not apply to this App.
9. International transfers
The App transfers no personal data across borders — because it collects and transmits nothing at all. The one exception is an inquiry email you send us voluntarily: that email is handled by the third-party provider of our mailbox (Google) and may be stored outside your country. That provider’s own policy applies; please avoid including sensitive personal data in emails.
10. Changes to this policy
If the App’s features or data practices change, we will update this page and revise the “Last updated” date at the top. For material changes (such as any future collection of personal data), we will make reasonable efforts to notify you prominently. Before material changes take effect, please rely on the newest version; by continuing to use the App you acknowledge the updated policy (where applicable law requires separate consent, we will obtain it in accordance with the law).
Questions, comments, or complaints about privacy or your data rights are welcome at any time; we usually reply within a reasonable period. You may also lodge a complaint with a supervisory authority in your jurisdiction (e.g., your national data protection authority, the California Privacy Protection Agency, Japan’s PPC, or the Cyberspace Administration of China).
