Privacy Policy

Last updated 21 September 2026

This policy explains what Vauxx Inc. collects when you use Vaux, why, and who else sees it.

What we collect

• Account details — your name and mobile number. The number is how you sign in; we send a one-time code to it.
• What you put in the app — trips, expenses, amounts, notes, flights, stays, and the people you share them with.
• Financial account data, only if you connect an account — balances and transactions, retrieved through Plaid. We never see or store your bank login.
• Messages — what you text to our number, and what we send you, so the assistant can act on it and keep the conversation in context.
• Usage data — pages opened and actions taken, so we can see what works and what breaks.

Who we share it with

We do not sell your data. We use a small number of processors to run the service:

• Plaid — connecting financial accounts.
• Twilio — sending verification codes and text messages.
• Linq — delivering our messages by iMessage and SMS.
• Maxi — running the Vaux assistant, which reads and replies to messages sent to our number.
• Google Firebase and Supabase — authentication, hosting and the database.
• PostHog — product analytics.
• Meta — advertising measurement on our marketing pages and signup screen, so we can tell which ads bring people to Vaux. This does not run on the pages that show your financial information.

Other members of a group see the trips and expenses you share with them. That is the point of the product, and it is worth remembering before adding a private note to a shared trip.

Cookies and tracking

We use cookies to keep you signed in and to measure how the product is used. Our marketing site also loads analytics and an advertising pixel. You can block these with your browser or an ad blocker without losing access to Vaux.

How long we keep it

We keep your data while your account exists. Ask us to delete your account and we remove your personal data, except anything we must keep for legal or accounting reasons.

Your choices

You can ask for a copy of your data, correct it, or have it deleted. Write to alecteller@gmail.com. You can disconnect a financial account at any time, and stop our messages by replying STOP.

Security

Data is encrypted in transit and at rest, and access is restricted to the people who need it to run the service. No system is perfectly secure; if a breach affects you we will tell you.

Children

Vaux is not for anyone under 18.

Changes

We will post any update here and change the date above.
