Privacy Policy

Last updated: September 2026

Stang is a personal finance app made by SMBee. We take your privacy seriously. Here is exactly what we collect and why.

What we collect

  • Account data — your email address, used only to identify your account.
  • Financial data you enter — transaction names, amounts, categories, and dates. Stored securely in Supabase (hosted on AWS) with row-level security, so only your account can read it.
  • Receipt images — photos or PDFs you attach to transactions are stored securely alongside your transaction data. Only you can view them.
  • Billing data — if you upgrade, payment is handled entirely by Stripe (web) or Apple (in-app purchase). We never see or store your card details.
  • Analytics — we use Google Analytics 4 on the public marketing pages only, never inside the app, to understand how people discover Stang. IP addresses are anonymised and ad personalisation is disabled.
  • Anonymous usage counts — if you try the web app without an account, it adds one to a daily total when certain things happen (for example, logging an expense or coming back on a later day) along with how many days you've been using it. Only the totals are stored. No cookies, account, device ID or IP address are attached, so the totals can't be traced back to you.

What we don't do

  • We don't sell your data.
  • We don't share your data with third parties beyond what's described here: Supabase for storage, Stripe and Apple for billing, and Anthropic's Claude for AI parsing and insights.
  • We don't track you inside the app — no analytics cookies and no per-person usage profile.

AI features

When you log an expense in natural language, scan a receipt, or ask Stang a question, the relevant text or image is sent to Anthropic's Claude API to generate a response. Anthropic's privacy policy applies to that processing. Your data is not used to train AI models.

Data retention & deletion

Your data is kept for as long as your account is active. You can delete your account and everything in it at any time from within the app — open Settings and choose Delete account. Deletion is immediate and permanent. If you would rather we did it for you, email hello@smbee.me and we'll process the request within 7 days.
