Vyselock is a self-control tool. It helps you stay off distracting and adult
content and keep to the focus commitments you set for yourself. This policy
explains exactly what the Vyselock browser extension accesses and what happens
to that information.
The short version: your browsing and everything Vyselock sees
on your screen stays on your own device. Vyselock never uploads, sells, or
shares it. The only information that ever leaves your device is a subscription
licence check, and only once you're on a paid plan.
What the extension accesses, and why
The pages you visit on a limited set of sites (X/Twitter,
Reddit, Instagram, LinkedIn, TikTok, Facebook). Vyselock reads the content of
these pages to detect sensitive/adult material and to hide the endless feed
when you've asked it to.
X/Twitter data responses. On X, Vyselock inspects the
site's own data responses for the platform's "possibly sensitive" flag, purely
to decide whether to show its block screen. This happens on your device and the
content is never stored or sent anywhere.
A floating focus-session timer on any page. When you unlock
a site for a timed focus session, Vyselock shows a small countdown so your
stated intent stays in view. It reads nothing from those pages; it only draws
the timer.
Local settings storage. Your schedule and lock state are
kept in the browser's own local storage on your device.
Where your information goes
Nowhere off your device. Vyselock has no cloud service that
receives your activity. The only thing the extension talks to is the Vyselock
helper program running on your own computer at the local
loopback address 127.0.0.1 (an address that never leaves the
machine). That local helper stores your streak, reasons, and block schedule in
files on your own disk.
Vyselock does not:
collect analytics or telemetry,
use tracking or advertising,
send your browsing history, page content, or personal data to us or any
third party,
take or upload screenshots.
Subscriptions and licence validation
During the initial pilot, Vyselock is free and performs no
licence check at all, so nothing whatsoever leaves your device.
After the pilot, Vyselock is offered on a paid basis (monthly, yearly, or a
one-time lifetime licence). To confirm that a subscription is active, the app
validates your licence. That validation transmits only your
licence key and an anonymous device identifier to our payment provider. It never
sends your browsing history, page content, or any record of what you looked at. Billing
itself (your card details, name, invoices) is handled entirely by the payment
provider under their privacy policy; Vyselock never sees or
stores your payment details.
A lifetime licence is validated the same way but does not expire.
Data retention and control
All Vyselock data lives on your device. Removing the Vyselock application and
extension removes it. There is nothing on our side to delete, because we never
receive it.
Permissions, in plain terms
Access to the listed sites:to detect sensitive content
and hide feeds on those sites.
Read tabs:to redirect a blocked page to the Vyselock
block screen.
Local messaging to the Vyselock helper:to read your
on-device block schedule and record blocked attempts, entirely on
127.0.0.1.
Local storage:to remember your settings.
Children
Vyselock is intended for adults setting limits for themselves.
