Privacy
We store what you give us: your profile, saved programs, notes, practice progress and the settings you choose. We do not sell personal data. Auth is handled by Supabase with encrypted sessions.
Analytics
To see which pages are useful, we may count page views with a privacy-friendly, cookie-free analytics tool. It sets no cookies, does not track you across other sites, and does not build a profile of you. We record the page address only — not the part after a “?”, which can hold search terms or sign-in codes — and never the admin, sign-in or profile pages. The tool sees your browser, device type, country and the site that referred you, as aggregate counts; it does not store your IP address.
Visitor analytics are currently switched off.
AI features
When you use an AI feature — Del, the Guide conversation partner, AI practice feedback, the Menu & Sign Decoder (the photo you upload) or pronunciation checks (your voice recording) — what you send is processed by the AI provider (Anthropic, or Microsoft Azure for speech) to produce the result. Decoder photos and voice recordings are not stored by us; for pronunciation checks we keep the scores and the text the checker heard (see The app, below). See how we use AI.
Del, your relocation assistant
Del is for adults: before first use you confirm you're 18 or over and accept how it works. We store that choice, the version you accepted and when. Del keeps no chat transcripts — the conversation stays in your browser or the app; each question is sent to Anthropic (our AI provider) only to answer it.
Memory is optional and off unless you turn it on. With it on, Del keeps short notes about your move (budget, income, family, pets, work, languages, timeline, climate, lifestyle, dream home, deal-breakers), with where each came from and a history of changes. Income, budget and family notes are only proposed until you confirm them; unconfirmed proposals are deleted after 7 days. Confirmed notes are kept until you delete them, and are sent to Anthropic with your questions so Del can tailor its answers. The change history is kept for up to a year; when you delete a note its text is removed from the history straight away.
With memory on, Del also keeps your profile up to date: when something you tell it — or an answer to one of its optional profile questions — fits a profile field used for matching (income, savings, people moving, age, work, languages, timeline, property plans, setting, climate, pets), it is written to your profile straight away and shown with an Undo. Del records each change (the field, the previous and new value, and when) so Undo can restore the previous value; that record is kept for up to a year and deleted when you turn memory off. Del never stores health, disability, religion, sexuality, ethnicity, political views, a criminal record, immigration, visa or citizenship status, legal matters, addresses or ID numbers — not on your profile and not in its notes — and never changes your citizenship or country from a chat.
With memory on you also get a daily in-app digest (you can pause it). It is built from your profile, your saved programs and your notes inside CasaSedora; only the list of program titles is sent to Anthropic to write its one-line summary. A record of what the digest already showed you is kept for 180 days so nothing repeats.
View, edit or delete any note — or all of them — under What Del knows about you. Turning memory off deletes every note and its history. All of it is included in Export my data and deleted with your account.
The CasaSedora app
The iPhone, iPad and Android app uses the same account and the same data as this website. It contains no advertising, analytics or crash-reporting tools and does not track you across other companies' apps or websites.
Push notifications. If you turn on rule-change alerts in the app, we store that phone's push token (a random device address issued by Apple or Google) and its platform. Alerts are delivered through the Expo push service and Apple or Google. The token is removed when you sign out of the app, turn alerts off, or delete your account.
Microphone (iPhone and iPad). The app asks for the microphone only when you tap Say it. The recording is sent to Microsoft Azure to score your pronunciation and is not stored by us. We do save the result to your account (the overall and per-word scores, the phrase, the language and the text the checker heard) so you can see your progress; it stays until you delete your account and is included in Export my data.
Pages such as this one open in your phone's built-in browser inside the app. You can delete your account from the app (Profile, Delete account) or on this website.
Who processes data for us
Supabase (database and sign-in), Vercel (hosting), Anthropic (AI answers), Microsoft Azure (speech), Expo with Apple and Google (push notifications), an email delivery service for sign-in and alert emails, and Stripe (payments on this website). They process data only to provide their service to us. Our hosting and database providers keep short-lived technical logs (such as IP address and device type) for security and reliability.
Adults only
CasaSedora is for people aged 18 and over, on the website and in the app. We don't knowingly collect data from anyone younger; if you believe a child has created an account, contact us and we will delete it.
Rule-change emails
If you save a program and we confirm a change to its official rules, we may email the address you signed in with. Sending uses an email delivery service (Resend), which receives only your address and the message. You can turn these emails off any time under Alerts on your profile.
Your data stays yours: download a copy of everything, or permanently delete your account, from Your data on your profile. Privacy questions: casasedora@gmail.com.
