Privacy Policy
XIANGYU Deep Video Converter is built to keep your footage on your own machine. This policy explains, in plain language, what data exists, who sees it, and why the answer is "almost nobody".
The short version: there is no upload code in the application, no telemetry, no analytics and no account system. Conversion runs as a local service on 127.0.0.1. We cannot see your videos, your files or how you use the app. The only personal data involved anywhere is what is required to process your payment and email you a licence key.
1. Data we handle, at a glance
| What | Who receives it | Why |
|---|---|---|
| Your video files and generated output | Nobody. They stay on your disk. | — |
| Usage / telemetry / crash data | Nobody. None is collected. | — |
| Email address, name, payment details | Our merchant of record (Creem) for international orders | To charge you, issue the invoice and comply with tax law |
| Licence key records | The Developer | To reissue a key if you lose it |
| Support emails you send us | The Developer | To answer your question |
2. What the application does
The Software is a Windows desktop application whose interface is served by a local HTTP
service bound to 127.0.0.1 — the loopback address, reachable only by programs on
your own machine. Every stage of processing, including model inference and video encoding,
happens in local processes.
- All model weights ship inside the installer, so there are no downloads at runtime.
- There is no analytics SDK, no crash reporter and no licence check that phones home.
- Activation is verified with an offline Ed25519 signature inside the application.
- The default installation listens only on the loopback interface, not on your LAN or the internet.
Practically speaking this means you can disconnect from the internet entirely and every feature continues to work, including activation.
3. What happens when you buy
We never touch raw card numbers. Payment is handled by a payment provider:
- International orders are processed by our merchant of record, Creem. It collects your payment details, applies any VAT / GST / sales tax required in your country, issues the invoice and handles disputes. We receive the information needed to fulfil the order — typically your email address, order identifier and purchase date — so that a licence key can be generated and emailed to you.
- Orders from mainland China may instead be processed through a domestic payment form.
We keep minimal purchase records (order reference, licence key issued, date) so that we can reissue keys and honour refunds. We do not build profiles, and we do not run advertising pixels on the payment pages.
4. What happens when you email support
Support is plain email. Whatever you write to us stays in the mailbox: luyingzhi2@gmail.com. We use it only to answer you and to diagnose the problem you describe. We do not add your address to any mailing list, and we do not send marketing email.
5. Website visitors
The product website at xiangyu.t-teams.uk is a set of static pages with no login, no comment system and no ad scripts. Standard web server logs produced by the hosting platform may record IP addresses and page requests; this is a property of the host rather than something we build into the pages.
6. What we do not do
- We do not sell, rent or trade personal data to anyone.
- We do not collect your footage, filenames or conversion statistics.
- We do not run advertising networks or behavioural tracking.
- We do not require an account, and we do not know how many videos you have converted.
7. Retention
Purchase and licence records are kept for as long as your licence is active, since a perpetual licence must remain verifiable indefinitely. Support emails are kept only as long as needed to resolve the issue. If you would like your records deleted, email us and we will remove what we are able to while preserving whatever is legally required for tax records.
8. Your choices and rights
Depending on where you live you may have the right to request access to, correction of, or deletion of the personal data we hold about you, and to object to certain processing. Email us and we will respond within a reasonable period. Because we hold so little data, in most cases the answer is simply that we have nothing beyond an order reference and a licence key.
9. Children
The Software is a general-purpose media tool and is not directed at children. We do not knowingly collect personal data from children.
10. Changes to this policy
If we ever change what we collect — for example by adding an optional update checker — we will update this page and revise the date at the top before the change takes effect. Making the app upload footage would contradict its entire purpose, and that is not going to change silently.
