Privacy Policy

• Messages you send to a Tabby group — the text is parsed to record expenses and answer commands like “balances”.
• Expense details — amounts, descriptions, who paid, and how a cost is split.
• Group and message metadata from WhatsApp needed to route replies and track delivery, including delivery/pricing status events from Meta.

We design Tabby to hold as little personal data as possible. Phone numbers and WhatsApp IDs are not stored in the clear: before anything is written to our database they are replaced with a one-way, salted pseudonym. The raw number is used only momentarily to deliver a reply and is never persisted. Display names shown in a group are stored only so Tabby can say who owes what.

We keep trip data only as long as it is useful, then delete it:

• One month after a trip is settled up (all balances clear), the trip and its expenses, participants and messages are deleted.
• One month of inactivity — if there are no new messages or expenses in a trip for 30 days, it is deleted.
• Delivery and pricing telemetry older than 30 days is also pruned.

Deletion is permanent and cascades to all related records. You can ask us to delete a trip sooner (see “Your choices”).

Data is used solely to provide the expense-tracking service — recording expenses, computing balances and settlements, replying in your group, and understanding our own messaging costs. We do not sell your data or use it for advertising.

Messages are delivered through Meta’s WhatsApp Business Platform and are subject to WhatsApp’s Business Terms and policies. We use reputable infrastructure providers to host the service. We do not share your data with anyone else except where required by law.

You can leave a Tabby group at any time. To request earlier deletion of a trip’s data, or to ask what we hold, contact us at hello@magicowls.co.

We may update this policy; the “last updated” date above reflects the latest version.
