What we collect
- Details you send us through the contact form, WhatsApp, email or phone: your name, business name, contact details and your message.
- Information needed to deliver a project, such as access to ad accounts, websites or social pages that you choose to share with us.
- Billing details needed to issue invoices and record payments.
How we use it
- To reply to you and prepare proposals.
- To deliver the services you hire us for, and to report on them.
- To issue invoices, keep accounts and meet legal and tax obligations in Bangladesh.
We do not sell personal information, and we do not use it for unrelated marketing.
Who we share it with
We share information only where it is needed to do the work: with the hosting and form provider that runs this website, with advertising and e-commerce platforms when we run campaigns or stores on your behalf, and with authorities when the law requires it.
Access to your accounts
When you give us access to an ad account, store or page, we use it only for the agreed work. You can remove our access at any time, and we will hand back any logins we created for you at the end of a project.
Cookies
This website does not use advertising or tracking cookies. Fonts are loaded from Google Fonts, which receives your IP address when the page loads.
How long we keep it
We keep enquiry messages for as long as they are useful for the conversation, and project and billing records for as long as Bangladeshi accounting and tax rules require.
Your choices
You can ask us to show, correct or delete the personal information we hold about you by emailing support@s4sit.com. We may need to keep some records where the law requires it.
