Privacy policy

Last updated: 11/05/2026

Who we are

This policy explains how Zellus collects and uses personal information when you use Zellus at https://zellus.bitsnax.net (the "Service"). We are responsible for the information described here. Contact us at support@zellus.bitsnax.net.

What we collect

Account details: your name, email address and password. Passwords are stored only as a one-way hash; we cannot read them.
Profile picture: if you upload one, it is stored with your account.
Sign-in and device information: for each signed-in session, your IP address, browser and operating system, and when the session was created and last used.
Security and activity records: sign-ins, failed sign-ins and changes to your account, with the IP address and device involved.
Billing records: your plan, subscription status, dates, and the amounts and dates of payments and refunds.
Files and content you add: anything you upload or enter in the Service.
Messages: notifications we show you in the Service and emails we send you.

Payment information

Payments are processed by Braintree or Stripe. Your card details go directly from your browser to the payment processor; they never reach our servers and we never store full card numbers. We receive and may show you the card brand, last four digits and expiry date so you can recognize the card on file. The processor's own privacy policy applies to the information it handles.

How we use it

To create and run your account and sign you in.
To keep the Service secure: limiting repeated sign-in attempts, showing you your active sessions, and investigating misuse.
To take payment for subscriptions, keep billing records and send receipts.
To send service emails such as password resets, receipts and payment notices. We do not send marketing email [unless you opt in].
To meet legal, tax and accounting obligations.

Cookies and browser storage

We use one essential cookie to keep you signed in. Your browser also stores your light or dark mode choice. We do not use analytics, advertising or tracking cookies. On the checkout and payment method pages, the payment processor's script may set its own cookies for fraud prevention.

Who we share it with

We do not sell or rent your personal information. We share it only with service providers that help us run the Service, under their own terms:

Payment processing: Braintree (PayPal) / Stripe.
Email delivery through SMTP relay, which sends our service emails.

The Service and its files are hosted on servers we operate in [country / state]. We may also disclose information when the law requires it, or to protect the rights and safety of our users or others.

How long we keep it

Account and profile: while your account exists, and deleted when you ask us to close it.
Sessions: until you sign out or the session expires.
Security and activity records: 365 days.
Notifications: 90 days.
Billing records: 7 years, as tax and accounting rules require, even after your account is closed.
Server logs: a short rolling window, typically a few days.

Security

All traffic uses HTTPS. Passwords are hashed, saved credentials for connected services are encrypted, and access to administrative functions is limited by role. No system is perfectly secure, so we cannot guarantee absolute security.

Your choices and rights

You can see and change your name, picture and password in Account, and sign out any of your sessions there. You can ask us to send you a copy of your information, correct it, or delete your account by writing to [privacy email]. We will answer within [30] days. Depending on where you live, you may have further rights, including the right to complain to your data protection authority.

Children

The Service is not meant for children under 18, and we do not knowingly collect their information. If you believe a child has given us information, contact us and we will delete it.

Changes to this policy

We will post any changes on this page and update the date at the top. If a change is significant, we will tell you by email or in the Service before it takes effect.
