Privacy Policy

Last updated: November 12, 2026

Uplein is a product of Varlein. This page explains what information Uplein handles, why, who helps us run it, and what choices you have. Questions: contact@varlein.com.

1. Two kinds of people

Business users create an account and send review requests. Their customers receive those requests. For the customer details a business uploads, the business decides why and how they are used and Uplein handles them on the business's behalf. Uplein does not use those details to market anything of its own.

2. What we handle

• Account: email address and password (the password is stored in a protected form by our sign-in provider, we cannot read it).
• Business details: business name, sender name, postal address, Google review link, time zone.
• Customer details a business adds: name, email address and optionally a phone number. A phone number is only stored for later. Uplein does not send text messages today.
• Consent records: when a customer was added, how, who recorded it, and the statement the business confirmed (that the customer agreed to be contacted by email).
• Message records: when an email was sent, whether it was delivered, bounced or received a complaint, and whether its review link was opened (time and the browser's identifier, called the user agent).
• Opt-out list: email addresses that unsubscribed, bounced or complained, so they are not contacted again.
• Technical logs: normal server logs (for example time, page and error information) used to keep the service working and secure.

3. Why we use it

To run Uplein: let businesses add customers, send the emails they choose, show what happened, respect opt-outs, keep the service secure, and answer support questions. We do not sell personal information and we do not use it for advertising.

4. Emails to customers

Every email names the business that sends it, shows its postal address and contains an unsubscribe link. Choosing "Unsubscribe" adds the address to that business's opt-out list. A link in the email goes through Uplein first so the business can see that it was opened, and then forwards to the business's Google review page. Opening a link is not the same as leaving a review; Uplein counts a review only when the business confirms it.

5. Who helps us run Uplein

• Supabase: database and sign-in (servers in the United States).
• Vercel: hosting of the web application.
• Resend: delivery of emails.
• Zoho: our own company mailbox (contact@varlein.com), used when you write to us.

These providers handle information only to provide their service to us. We may add or replace providers.

6. How long we keep it

We keep account and customer information while the account is active. When a business removes a customer, we keep a hidden record so the proof of consent and the opt-out status stay intact. Opt-out entries are kept so that people who unsubscribed are not contacted again. You can ask us to delete an account or specific information (see section 8).

7. Security

Each business can see only its own data; this is enforced in the database itself. Connections are encrypted. No online service is perfectly secure, so we cannot promise absolute protection. If we learn of a breach that affects you, we will tell you as the law requires.

8. Your choices

• Customers: use the unsubscribe link in any email, or write to the business that contacted you. You can also write to us.
• Businesses: you can edit or remove customers in the app and ask us to delete your account.
• Depending on where you live you may have rights to see, correct or delete your information. Write to contact@varlein.com and we will respond within a reasonable time.

9. Children

Uplein is for businesses and is not meant for children. We do not knowingly collect information from children.

10. Changes and contact
