Privacy Policy

The short version. If you only browse this site, we collect nothing about you beyond what any web server sees to deliver a page. We run no analytics and set no tracking or advertising cookies. If you subscribe, we keep your name, email and subscription details so we can give you access, and we never sell any of it.

1. Who we are

This policy covers silt-seb.com and the S.E.B. client portal, operated by Sentient Index Labs & Technology (“SILT”, “we”). Contact: info@sentientindexlabs.com.

2. If you only browse

• No analytics and no tracking. We do not use analytics services, advertising networks, tracking pixels or tracking cookies.
• One setting in your browser. If you choose a light or dark theme, that choice is saved in your own browser so the site remembers it. It never leaves your device.
• Standard server data. Our hosting provider necessarily processes technical request data, such as IP address, browser type and the page requested, to deliver and secure the site. We do not use it to identify or profile you.

3. If you subscribe

Payment is handled by Stripe. We never see or store your card details. From your checkout we receive and keep:

• your name and email address;
• your Stripe customer and subscription identifiers, your plan, and what it gives you access to;
• a portal username, created from your email address.

Your password is stored only as a one-way cryptographic hash, which we cannot reverse. When your account is first created, a temporary password is kept for up to 24 hours so it can be sent to you, and then expires. To protect accounts, we count failed login attempts.

Delivered data is marked. Evaluation data delivered to a subscriber carries a watermark that identifies the receiving account, so an unauthorised copy can be traced. This is described in the Subscriber Agreement.

4. If you email us

We keep your message and address to reply to you. Our email is provided by Google Workspace.

5. Why we use it

Only to provide the service you asked for: to give you access, bill your subscription, answer you, keep accounts secure, and enforce the Subscriber Agreement. We do not sell or rent personal information, and we do not share it for advertising.

6. Who processes it for us

• Stripe: payments and billing records
• Vercel: website hosting
• Upstash: the database that holds account and subscription records
• Google Workspace: email

These providers may process data in the United States and other countries where they operate.

7. How long we keep it

After a subscription ends, your account and vault are kept for a 30-day grace period so the subscription can be reactivated without loss, then permanently deleted. Ask and we will delete them sooner. Stripe keeps billing and transaction records for as long as tax, accounting and legal obligations require. These terms match the deletion section of the Subscriber Agreement, which controls if the two ever differ.

8. Your choices

You can ask us to show you, correct, or delete the personal information we hold about you by emailing info@sentientindexlabs.com. Depending on where you live, you may have further rights under local law. We will respond to any request we receive.

9. Security

We store passwords only as hashes, restrict access to subscriber data to the account it belongs to, and hold payment details only with Stripe. No system is perfectly secure, and we will tell affected subscribers promptly if we learn of a breach involving their information.

10. Children

The site and service are intended for businesses and professionals and are not directed at children under 16.

11. Changes

If what we collect changes, this page changes first. The date at the top shows the latest update. See also our Terms of Use.
