Kira helps a group split a restaurant bill: the person who paid photographs the receipt, shares one link, and everyone taps what they had. This page explains what Kira keeps and why. Kira is a small personal project, run in Malaysia, and it is in testing.

Kira never touches money

Friends pay the person who paid the bill directly, with their own bank or e-wallet. Kira only shows who owes what.

If you paid the bill (the organizer)

Sign-in: your name and email address from Google, or your phone number if you sign in by SMS. Kira does not get access to your Gmail, contacts, files or anything else in your Google account.
Your bills: the receipt photo, the items and prices, the names you add, and the payment details you choose to show your friends (account name, bank, account number, and your DuitNow QR picture).
Receipt photos are sent to Google's Gemini service to read the items. Card numbers and similar payment details on the receipt are covered in black before the photo is saved. Check the photo before you share.

If a friend sent you a bill link

You don't need to sign up. Kira keeps the name you choose or type, what you tapped, and whether you said you've paid.
Locking your name (optional): if you sign in with Google on a bill, Kira keeps your name and email address from Google and links your account to your name on that bill, so nobody else can use it. Your bills then show up when you sign in, and, if you add it, in a calendar subscription that only you have the link to.
Your phone remembers which name is yours on that bill, so you don't pick it again. Clearing your browser forgets it.
Email reminders (optional): if you ask Kira to email you when you haven't paid, it keeps your email address for that bill only. It sends at most three reminders, three days apart, and deletes the address when you tap “I've paid”, when the bill is settled, after the last reminder, or when you tap “Stop these reminders” in the email.
Calendar reminders you add are saved in your own calendar app. Kira doesn't keep anything for them.

Who can see a bill

Anyone who has the bill's link can see it: the items, who tapped what, everyone's share, the receipt photo and the payment details. That is how the group splits it, so only share the link with the people at the table. Bill links are long and random, and are kept out of search engines.

Usage and error information

To find out where people get stuck, Kira records anonymous usage: which screens were opened, how long they stayed on screen, which buttons were tapped, and whether something failed. This uses a random code for your browser, not your name, phone number, email, amounts or IP address. If something breaks, an error report is sent to Sentry with bill links and phone numbers removed.

Services Kira uses

Supabase (database and photo storage) and Vercel (hosting), in the Asia-Pacific region.
Google (sign-in, and reading receipt photos with Gemini).
Sentry (error reports) and, for SMS sign-in, Twilio.
Resend, to send the optional email reminders.

Kira has no ads and does not sell or share your information for marketing.

Keeping and deleting

Bills are kept so the group can come back to them. To have your bills, your account, or your name on a bill deleted, or to ask what Kira holds about you, email jeremykiuwx@gmail.com. You can also ask for this under Malaysia's Personal Data Protection Act.
