Privacy
Sialk holds as little personal data as it can. That is the cheapest compliance
strategy available and also the honest one, so this page is short.
Last updated: 25 August 2026.
## Who is responsible
Sialk is run by **Bashir Zahedi**, an individual based in the United Kingdom,
who is the data controller for the purposes of UK GDPR. A company is expected to
be incorporated before the first public release of the application; this page
will be updated to name it when that happens.

## This website
**Nothing on this site is recorded.** There are no analytics, no cookies, no
tracking pixels, and no third-party scripts other than the web fonts named
below. You are not asked to identify yourself and nothing asks you to sign in.
**The microphone demos process audio entirely in your browser.** The inspector
and the example sketches read your microphone to draw what they draw. That audio
is analysed on your own machine and is never recorded, stored, or transmitted
anywhere — not to Sialk, not to anyone. Closing the page ends it. You can verify
this: the source is public and the page makes no network requests while running.
**Fonts** are served by Google Fonts, which receives your IP address as a
consequence of your browser fetching them. That is the only third party this
site involves.
**Hosting and server logs.** This site is hosted by **Vercel Inc.**, a company
based in the United States, which acts as a data processor under its Data
Processing Addendum. Bashir Zahedi remains the controller.
Serving a page to you means Vercel receives **your IP address, location
information derived from it, and basic information about your browser and
device** — the ordinary consequence of any web request reaching any server.
Vercel uses it to deliver the site and to protect it from attack.
Vercel does not publish a fixed retention period for this, stating only that it
keeps information "for the minimum necessary period to fulfil our legal and
contractual obligations". That is their answer rather than a number, and it is
repeated here as such rather than dressed up as one. Their notice is at
<https://vercel.com/legal/privacy-notice>.
**No analytics are switched on.** Vercel offers Web Analytics and Speed
Insights; neither is enabled for this site, so no page views, sessions or
performance samples are collected.
**Your data leaves the UK.** Vercel processes in the United States. Transfers
are covered by the standard contractual clauses in their Data Processing
Addendum. If that is not acceptable to you, the site can be read without
JavaScript and nothing here requires you to identify yourself.
## The Sialk application
Not yet released. When it is, this section will apply and will be updated before
it does.
- **Data held:** your email address, the name on your subscription, and the state
of that subscription. Nothing else.
- **Payment details are never touched by Sialk.** Purchases are handled by
Paddle, who become the seller and hold all payment information. Their privacy
terms apply to that part.
- **Telemetry is opt-in and off by default.** If you switch it on, it is
anonymous and its purpose is explained at the point you are asked. It is never
enabled without you choosing it.
- **Your work is yours.** Sketches, shows and anything made with Sialk belong
entirely to you. Sialk does not upload, inspect or store them.
## How long data is kept
For as long as your subscription runs, and then for as long as tax and
accounting law requires records of the transaction. [[CONFIRM(subscription): the retention
period with your accountant — UK company records are commonly six years.]]
## Your rights
You can ask what is held about you, ask for it to be corrected, ask for it to be
deleted, and object to how it is used. Write to the address above and you will
get an answer within one month.
If you are not satisfied, you can complain to the Information Commissioner's
Office at ico.org.uk.
[[CONFIRM(subscription): whether ICO registration is required and complete it if so. Flagged
UNVERIFIED in 12 §8.]]
## Changes
If this policy changes materially, the change will be described here with the
date. The version you agreed to when you subscribed continues to apply to you
until you are told otherwise.
