Privacy Policy
Multi-Account Switch · Last updated: 2026-04-21
This policy describes how the Multi-Account Switch browser
extension, its landing page (product.xyptkd.cn) and its backend
service (my-admins.xyptkd.cn) collect, use, store and protect your
personal information. By installing or using the extension you are
deemed to have read and agreed to this policy.
1. Information we collect
-
Account email & password: entered when you
register for Pro. Passwords are stored as bcrypt hashes; we never
see or store plaintext passwords.
-
Order & payment info: merchant order number,
payment channel (WeChat / Alipay), amount, paid/refunded
timestamps, channel-side transaction IDs. We do not have access to
your card / Alipay / WeChat credentials — payment happens entirely
on the third-party channel.
-
Device fingerprint: a random UUID generated by
the extension on first install (stored in browser local storage),
used to enforce the "up to 3 devices" Pro binding rule. No
hardware identifiers (MAC / IMEI / IP geolocation) are collected.
-
Account snapshot data: per-site cookie snapshots,
group names, profile names you create in the extension —
stored only in your local browser storage; never uploaded
to our servers.
2. Information we do NOT collect
- No URLs or browsing history
- No inspection of the contents of your cookie snapshots (cookies are only used locally to switch accounts)
- No hardware IDs, MAC addresses, IP geolocation
- No third-party analytics (no Google Analytics, no embedded telemetry SDKs)
3. How we use the information
- Email: for sign-in and essential service notifications (e.g. order anomalies)
- Orders: to grant Pro entitlement, reconcile accounts, and handle refunds
- Device fingerprint: to enforce the Pro device binding cap
- Snapshot data (local): to power the core "switch accounts per site" feature
4. Where your data lives
-
Local (browser storage): snapshots, groups,
device fingerprint, access_token. Cleared automatically when you
uninstall.
-
Our server (my-admins.xyptkd.cn, hosted on
Alibaba Cloud Mainland China): account email, hashed password,
order records, entitlements, device binding summary.
5. Sharing
We do not share your information with any third party except:
-
Necessary data is passed to the payment channel (WeChat Pay,
Alipay) to complete the transaction — limited to merchant order
number, amount and product name.
- When required by law or a valid legal process.
We do not sell, rent, or share your data for
marketing purposes.
6. Your rights
- Access & export: view your order history and entitlement status in the extension's options page.
- Delete your account: email support to request deletion; we will delete your account email, anonymize orders, and remove entitlements and device bindings within 7 business days.
- Unbind devices: do it yourself in the extension or request via support.
- Refund: email support if eligible; refunds go back via the original payment channel.
7. Data retention
Account emails and order records are kept long-term to support
refunds and accounting. Entitlements are kept 3 years after
expiration or revocation for audit. Device bindings retain only
unbind logs after you unbind. Account deletion triggers cleanup.
8. Security
- HTTPS everywhere (Let's Encrypt)
- Passwords stored as bcrypt hashes, never plaintext
- JWT access tokens with 30-day expiry
- Admin panel path obscured + independent strong password
- Database runs on our own server, not third-party SaaS
9. Children's privacy
This service is not directed to children under 14. If you are a
guardian and discover a minor using the service, please email us
and we will delete the related data promptly.
10. Changes to this policy
We will publish updates on this page and update the "Last updated"
date. Material changes will be notified via your registered email.
Continued use of the service constitutes acceptance.
