Privacy at Casita
Last updated November 10, 2026
The short version
- Casita keeps your family’s plans and your house’s records so your family can use them. That’s the only reason we have them.
- No ads. We don’t sell your information or share it with advertisers.
- You can download everything, any time, and a parent can delete the household with 14 days to change their mind. Anyone can delete their own account in the app.
- A few services help us run Casita, like our hosting and email. Each gets only what it needs for its job.
Who we are
Casita is made by FastSail Technologies LLC (“we”). If you have a question about your information, write to hello@usecasita.app.
What we keep, and why
- Your account. Your email address and your name. We sign you in with a 6-digit code sent to your email, so there’s no password to keep.
- Your household. Whatever your family puts in Casita: the people in it (including any children’s names and birthdays you choose to add), pets and their care, the calendar, to-dos and chores, meals, recipes and groceries, lists, trips, gifts and saving goals, records about your house and the people who work on it, documents and photos you upload, and notes for sitters, including your door code if you add one.
- Your settings and devices. Your notification choices, and, if you turn notifications on, a token that lets us send them to your phone. Read-only keys you create for widgets and Siri Shortcuts.
- Casita Plus. If your household subscribes, which plan it’s on, when it renews or ends, Apple’s transaction number for it, and who in the household started it. Apple or Google takes the payment: we never see your card or your account with them.
- Calendars you connect. If you connect a Google or Outlook calendar, permission to read it. If you subscribe to a calendar by link, such as your school’s, that link.
- Email you forward to your household’s address, so Casita can suggest events and to-dos from it for you to check.
- The waitlist. If you join it on usecasita.app, your email address and where you signed up. We use it for one thing: telling you when Casita is ready.
- Server logs. When you use Casita, our servers record technical details such as your IP address and what was requested, to keep Casita running and secure. These logs are capped in size and replaced as new ones come in.
- Invites from other families and partners. If you type your email on an invite page (usecasita.app/r/…), we keep it for up to 30 days, only so the household you set up with that email gets its two free months. When a household starts through someone’s invite, we keep that it did, and who the invite was from, so they can be rewarded if your household subscribes yearly. They see only how many households came and subscribed, never who.
- Event invites. If your household invites other families to an event, its invite page (usecasita.app/e/…) shows the event’s title, day and time, the host’s first name and the town you choose. The address shows only to people who say yes. Families who answer give a name, whether they’re coming, how many adults and kids, and, if they like, a note and an email for changes and a reminder. They don’t need an account. Only your household sees their answers; other guests see how many are coming, and first names only if you turn that on.
- If you earn referral rewards, or you’re a partner. Your code, what you’ve earned and been paid, and, for partners, your name, email and application. To pay you, Stripe collects your identity, bank and tax details under its own policy; we keep only the ID Stripe gives your account.
- Which days you use Casita. One note for each day you use the app while signed in, and whether it was on iPhone, Android or the web. We look at these only in total, to see whether Casita keeps being useful (for example, how many people come back the week after they join). They stay on our own servers, aren’t shared with anyone and aren’t used for ads.
We don’t use advertising or third-party analytics trackers, and our website doesn’t use cookies to follow you around. The app keeps you signed in by storing a sign-in token on your device.
Who in your household sees what
- Parents see everything in the household, including money: budgets, costs and saving goals. Nobody else sees money, and a parent can keep a saving goal private to themselves.
- Family and kids see what their role allows. A child can only have their own sign-in if a parent invites them.
- Sitters see only what they need for the days they’re booked, through a link that works without an account. A door code shows only on the day it’s needed.
- Families you invite to an event see only its invite page: never your calendar, address (unless they say yes), money or anything else in Casita.
- The next owner of your house sees nothing unless a parent chooses to make a packet of the house’s records when you sell. Family plans and notes never go with it.
Services that help us run Casita
We share information with these services only so they can do their part, and only what each needs.
We never sell your information, and we don’t share it with advertisers. We’ll only disclose it beyond these services if the law requires us to, or to protect someone’s safety.
How we protect it
- Everything travels over encrypted connections (HTTPS).
- Your door code and your connected calendars’ access are encrypted in our database.
- Sign-in uses one-time codes, so there’s no password that could leak.
- Sitter links work only for the days they cover, and widget and Siri keys can only read.
- Only the people who run Casita can reach our servers.
No service is perfectly secure. If something ever goes wrong that affects your information, we’ll tell you.
How long we keep it
- Your household’s information: for as long as your household uses Casita.
- When a parent deletes the household: you have 14 days to change your mind, then it’s deleted. Copies in our backups are gone within 4 weeks after that.
- When you delete your account: your login, sign-ins, phones and the days you used Casita are deleted right away, and you leave every household. What you added stays with your family, under your name, without a login. Copies in our backups are gone within 4 weeks.
- Forwarded emails: deleted after 30 days.
- Emails typed on invite pages: cleared once your household is set up, or after 30 days if it isn’t.
- Answers to event invites: deleted, emails included, 30 days after the event. The household keeps only the counts.
- Referral rewards and payouts: kept as long as the law requires for our accounts and taxes, even after an account or household is deleted, but without anything about the family.
- Waitlist emails: until you ask us to remove yours.
Your choices
- Download everything, any time, from Settings: the calendar, lists, recipes and records.
- Change or delete anything you’ve added.
- Delete your household, if you’re a parent, from Settings.
- Delete your account, from Settings › Your account. If you’re the only parent in a household, you make someone else a parent, or delete the household, first.
- Turn off any kind of notification, or set quiet hours.
- Ask us what we hold about you, or to correct or delete it, at hello@usecasita.app. We’ll answer within 30 days. Depending on where you live, you may have further rights under local law, and we’ll honor them.
Children
Casita is for families, and parents are in charge of it. Children’s information is added by a parent, and a child can only have their own sign-in if a parent invites them. Casita never shows ads to anyone, children included. If you believe a child’s information is in Casita without a parent’s permission, write to hello@usecasita.app and we’ll delete it.
Changes to this policy
If we change this policy in a way that matters, we’ll tell parents by email and in the app before the change takes effect. The date at the top always shows the latest version.
