Privacy policy

Last updated 11 November 2026

Sagashi (ABN 53 838 751 348) keeps only what it needs to read your property alerts and tell you which listings fit what you asked for. It never sells your information and never uses it for advertising.

Questions or requests: privacy@sagashi.au.

What Sagashi keeps

Your account. Your email address, and a password if you chose one. The password is held only as a one-way hash by our sign-in provider; Sagashi never sees or stores it. If you sign in with Google, Google shares your name, email address and profile picture with our sign-in provider, and Sagashi uses your email address to identify your account and to write to you.
Your preferences. What you told Sagashi you want: budget, suburbs, the kind of area and whether to avoid major development nearby, rooms, where you commute to and when, the schools whose zone you want, the kinds of school you'd like to know the nearest of and how far you'd travel to them, the kinds of childcare you need in the suburb, the places you'd like nearby, and your own description of the home you picture. Kept until you change them or your account is deleted.
Your alert address. The private address Sagashi gives you, which your realestate.com.au or Domain account sends its property alerts to.
Mail sent to that address. Each message is read, then deleted. What Sagashi keeps is what the alert said about each listing (address, price as written, rooms, the portal's link), that the alert reached you, and when. A listing that reached Sagashi only in your alerts is never shown to anyone else, and nothing shows another buyer whose alert brought a home. Mail from anyone but realestate.com.au and Domain is discarded unread. Their codes and email verifications are passed on to you, below. A message Sagashi could not read is kept so it can be read once the reader is fixed, and is then deleted like the rest.
Codes passed on to you. When a portal's code (to sign up or sign in, or to confirm a new email address) or its email verification reaches your alert address, Sagashi shows you the code, or the verification link while it can still be used, in Activity, and emails it to you too. It deletes its copy of the code or link after one day.
How far each portal's setup has got. When a portal sends your alert address a code or link, realestate.com.au confirms that it is now your account's email, or you open Domain's verification link from Sagashi, Sagashi also keeps only which portal, which of these happened, and when, so it can show how far that portal's setup has got, and deletes that after 30 days. Other notices a portal sends about your account are discarded unread.
A confirmation code. When you sign up with an email address and a password, our sign-in provider emails you a code to confirm the address is yours. The code and its expiry are kept by our sign-in provider, never by Sagashi.
Commute answers. For public transport, which Sagashi works out itself from the public timetable, the journey's minutes, or that no stop is within walking distance, never the route. These answers are kept against the listing and the destination and time, name no one, and are deleted after 30 days, or sooner when the timetable they came from is replaced. A driving or cycling journey is looked up only when you open a home's commute row, before or after you have an account, and nothing about it is kept.
A listing's position, worked out from the address the alert gave, so its map and commute can be checked.
Public development applications from the NSW Planning Portal, to show what is proposed near a listing. They name no one, and nothing about you is sent to get them.
Public school data: the NSW Department of Education's school zones, school facts and enrolments, and ACARA's list of Catholic and independent schools, to show the schools near a listing and check the zones you chose. They name no one, and nothing about you is sent to get them.
Public family data: approved childcare services and their ratings from ACECQA's national registers, 2021 Census figures for small areas and suburbs from the Australian Bureau of Statistics, and recorded crime by suburb from the NSW Bureau of Crime Statistics and Research. They name no one, and nothing about you is sent to get them.
What the NSW planning maps show at a listing: its zoning, heritage, bushfire prone land and aircraft noise. These name no one, are shared by everyone the listing reached, and are checked again every 90 days.
Answers during a Google sign-up. If you finish onboarding by signing in with Google, your answers are held for at most ten minutes while Google signs you in, then saved to your account and the held copy deleted.
When you last opened Activity, so Sagashi can show what's new.
Server logs, including your IP address, which our host keeps for a limited period to run and protect the service.

What Sagashi never keeps

Listing pages. Sagashi never visits the portals; it links you to them. From the agency websites named on the Data sources page it keeps only a listing's facts, such as its address, rooms and price as written, never the page, its description or its photos.
Your description while you are still setting up. Sagashi reads it to show you what it recognised, and keeps it only as part of your preferences once you create your account.
Your answers before you have an account. On the last step, Sagashi uses them to find the homes that fit and to show those homes' screens, and keeps nothing of them: not stored, not logged and not linked to you. They are kept only once you create your account, as your preferences.
Your answers given through an AI assistant. When you ask ChatGPT, Claude or another assistant connected to Sagashi which homes fit, the assistant sends Sagashi the answers to check, and Sagashi keeps nothing of them: not stored, not logged and not linked to you. What the assistant keeps of your conversation is up to its provider, under its provider's own policy.
Anything about nearby places. What is nearby is Google's own map, shown in your browser when you open a listing's Nearby row.
Routes, or the times of driving and cycling journeys.
Your portal passwords. Sagashi never asks for them.
Anything in your browser's storage. Sagashi uses only its own sign-in cookies, which scripts cannot read, and no tracking or advertising cookies.

How the app is measured

A public question page sets no cookie, runs no script and keeps nothing about you.

To see how Sagashi is used and how fast it is, the app sends PostHog a short note when you open a screen, open a listing or one of its rows, follow a link to a portal, or wait more than a second, and when the app shows an error, and once when you arrive without being signed in. Each note says only which screen, which row, how long it took, which kind of error, or how you arrived: from a search engine, an AI assistant, Sagashi's own site or directly, and whether through a public question page. The address you came from is reduced to one of those and is not sent or kept. It never says who you are, your email, your answers, or anything about a listing: no address, price or suburb. Nothing is stored in your browser for it, and your visits are not linked together. Your IP address passes to PostHog so it can count visitors without cookies, and it is not kept.

Who else handles it

Sagashi uses these services to run. Each handles your information only to provide its part.

Neon: the database and sign-in, in Singapore.
Render: the server that runs Sagashi, in Singapore.
Cloudflare: receives mail sent to your alert address, runs the domain, and fetches agencies' listing pages for Sagashi. Nothing about you is sent to fetch them.
Resend: sends Sagashi's emails, such as password resets, codes, and the setup steps you ask to have emailed.
PostHog: receives the notes above about how the app is used and how fast it is, in the European Union.
NSW Government planning service: a listing's position, and nothing else, is sent to look up its zoning, heritage, bushfire and aircraft noise maps. Nothing about you is sent.
Google: listing addresses that Sagashi's own copy of the national address file (G-NAF) can't place, listings' positions and your commute destination are sent to Google to place them on a map and check driving and cycling journeys, without your name or email address. Public transport journeys are worked out by Sagashi itself, from Transport for NSW's public timetable, so nothing is sent to Transport for NSW. A listing's maps are Google's, loaded in your browser. When you open a listing's Nearby row, your browser asks Google's map for the kind of place you chose near that listing's address. Google also signs you in if you choose it.

Some of these services process information outside Australia, including in Singapore, the United States and the European Union.

Seeing, correcting or deleting it

You can see and change your preferences in the app at any time. To get a copy of what Sagashi holds about you, or to have your account and everything linked to it deleted, email privacy@sagashi.au from the address you signed up with. Sagashi will do it within 30 days and tell you when it's done. A listing that also reached another buyer stays for them, without any link to you.

Children

Sagashi is for adults buying property. It is not meant for anyone under 18.

Changes and complaints

If this policy changes, the date at the top changes too. If you're unhappy with how Sagashi has handled your information, email privacy@sagashi.au. If that doesn't resolve it, you can contact the Office of the Australian Information Commissioner.
