Who we are
Silai (silai.app) is operated by Silai Arts Inc., a Canadian company
("Silai", "we"). Questions about this policy or your data:
hello@silai.app.
What we collect
- Account details: name, email address, and a securely
hashed password (we cannot see the password itself). Tailor shops also
provide shop name, phone and WhatsApp numbers, and city.
- Body measurements: the numbers produced by the camera
scan or typed in by you, plus optional details you provide such as
height, underbust (bra band) size, weight, age, or cup size.
- Scan video frames: the short video you record is
reduced to a set of still frames used to estimate your measurements.
These frames are deleted automatically once processing completes; failed
or abandoned scans are cleaned up within 2 days. A mathematical body
model derived from the scan may be retained; the original imagery is
not.
- Scan pose landmarks: for each video frame the scan
looks at, the positions of 17 body joints (shoulders, hips, knees and
so on) as numbers, plus the outline width of the cut-out at 64
heights, and the phone's tilt angles while it recorded. No pixels. We
keep these with the scan to check and improve how the scanner is
trained on the way people really stand, turn and prop the phone.
- Scan outlines: for each frame the scanner used, a
line drawing of your silhouette at 420 by 420 pixels, the same
outline the measurement model reads. No photo pixels, no face, no
background. We keep these with the scan to train the model to give
the same measurements every time a person scans, using scans from
real phones in real rooms.
- Listings, orders and messages: what you post, order
enquiries you send or receive, chat messages, ratings, and the city and
approximate coordinates you attach to listings (shown publicly).
- Technical basics: server logs (IP address, browser
type, pages requested) kept for security and debugging. A scan taken
without an account also keeps the IP address and device type it was
uploaded from alongside the scan, so we can tell scans apart and spot
automated abuse; that address is removed after 90 days.
How we use it
To run the marketplace: estimating and storing your measurements, showing fit
scores, connecting buyers with sellers and tailors, sending
transactional email (verification, order and message notifications), and
keeping the platform safe, including automated screening of uploaded
photos. We do not sell personal data, and we do not send marketing email
to customers.
Who sees your measurements
Only you, and any tailor or seller you choose to send an order enquiry
to. A Pre-Loved listing shows the garment's measurements, never your
body's; fit scores are computed for your eyes only. Public listing pages
show whatever you put in them, including the city you attach.
Cookies, ads and analytics
Silai is free because pages carry advertising served by Google AdSense,
which uses cookies and similar technologies; in the EEA, UK and
Switzerland you will see a consent choice before any such cookies are
set, and you can decline personalised ads there. We also use Google
Analytics to understand overall traffic. Session cookies keep you signed
in; they are essential and hold no tracking data.
Payments
Silai processes no order payments; you pay tailors and sellers directly.
The only payment on Silai itself is the optional listing boost, handled
entirely by Stripe; your card number never touches our servers.
Where your data lives
Silai runs on Amazon Web Services in the United States. Service
providers we rely on: AWS (hosting, storage, email delivery, automated
image screening, measurement processing), Google (advertising,
analytics), and Stripe (boost payments). Each receives only what its
function needs.
Retention
- Scan frames: deleted after processing, at most 2 days.
- IP address kept with a scan taken without an account: removed after
90 days.
- Scan pose landmarks, outlines and outline statistics: kept with
the scan and deleted with it.
- Scans you stop using: removed after 365 days; your most recent scan
is always kept so your measurements stay available.
- Pre-Loved listings: deleted automatically 365 days after posting,
photos included.
- Accounts, orders and messages: kept while your account exists.
Your choices
You can edit or delete your listings and re-scan or retype your measurements at
any time. To delete your account and its data, email
hello@silai.app
from the address on the account and we will remove it within 30 days,
except records we must keep for security or legal reasons. Silai is not
directed to children under 16.
Changes
If this policy changes materially, the date above changes with it and
significant changes will be announced on the site.
