Privacy Policy
Chasein (“we”, “us”) is an invoice reminder service for freelancers and small businesses, operated from Skopje, North Macedonia. This policy explains what personal data we handle, why, and what your choices are. Questions: support@chasein.app.
Who is who
- You are the person or business that subscribes to Chasein.
- Your clients are the people you add to an invoice so Chasein can send them reminders.
For your own account data, we decide how it is used. For your clients’ data, you decide what is added and why, and we process it only to send the reminders you set up. You are responsible for having a lawful reason to contact your clients about invoices they owe you.
What we collect
- Account data: your email address, and your subscription status (we receive an identifier and status from Whop, our payment provider).
- Invoice data you enter: client name, client email address, invoice number, amount, currency, due date, your payment link or bank details, your business name, and reminder settings.
- Reminder records: which reminders were scheduled and sent, and when.
- Login data: one-time login link tokens (stored only as a hash and valid for 15 minutes) and a session cookie that keeps you signed in.
- Technical data: standard server and security logs (for example IP address and request time) kept by our infrastructure providers.
We do not collect your card details. Payments are handled entirely by Whop. We do not receive or hold the money your clients pay you, and we do not use advertising or analytics trackers.
How we use it
- To provide the service: sign you in, store your invoices, and send reminder emails (with an invoice PDF if you choose) to your clients on your schedule.
- To manage your subscription and verify that your account is active.
- To keep the service secure, prevent abuse, and fix problems.
- To email you about your account, such as login links and important service notices.
We do not sell personal data.
Who we share it with
We use a small number of service providers who process data on our behalf:
- Whop – checkout, billing and subscription management.
- Cloudflare – website hosting, database storage and DNS.
- Resend – delivery of login emails and reminder emails.
These providers may process data in countries outside your own, including the United States and the European Union. We may also disclose data if the law requires it.
Cookies
We use one essential cookie to keep you signed in. We do not use advertising or tracking cookies.
How long we keep data
We keep your account and invoice data while your account exists. When you ask us to delete your account, we delete your account, invoices and reminder records. Some records may remain briefly in backups or provider logs, and we may keep information we are legally required to retain.
Your rights
Depending on where you live, you may have the right to access, correct, export or delete your personal data, to object to or restrict certain processing, and to complain to your data protection authority. To use these rights, email support@chasein.app from the address on your account. If you are one of our users’ clients and you no longer want invoice reminders, contact the business that sent them; you can also email us and we will pass your request on or act on it.
Security
Data is transmitted over HTTPS, login tokens are stored hashed, and access to our systems is restricted. No system is completely secure, so we cannot guarantee absolute security.
Children
Chasein is for businesses and is not directed at children under 16. We do not knowingly collect their data.
Changes
If we change this policy in a meaningful way, we will update the date above and, where appropriate, tell account holders by email.
