Who runs homie
homie is an independent tool for people buying, renting or owning a flat in Catalonia. This is a trial site, still being tested; how to reach whoever runs it is at the end of this section. It is not part of, and is not endorsed by, any public body, register or company named on this page.
For your data, privacy or a security problem, write to privacy@texthomie.com · for anything else, info@texthomie.com
What homie stores about you
The flats you check: the address, floor, door and stair you type, the nickname and asking price you give them, which side the windows face, whether there is a lift and the state the flat is in. Every fact homie pulls about those addresses from public registers, with its source and date, so the report can be shown again without asking the registers twice.
What you add to a flat: a floor plan (the traced plan and a reduced copy of the image you uploaded), photos from a visit (kept in private storage that only you can open) and corrections you make to a figure. Documents you add are read once for their facts: before anything leaves your device, names, ID numbers, phone numbers, e-mail addresses and bank accounts are replaced with placeholders; homie keeps the facts it found and a three-line summary, and never the text of the document.
If you sign in with Google, the name, email address and profile picture your Google account shares, which flats belong to your account, and the preferences you give (budget, size, what matters to you). Signing in is optional; without it, the flats you check belong to this browser.
Questions you ask homie on the site are sent to a language model to be answered. homie keeps each question with its answer, the flats it was about and your account or this browser for ninety days, so it can see how the chat is used and make the answers better, then deletes them. It also keeps what each answer cost, so the service can stay within its budget.
To keep the service from being abused, homie counts actions such as new flats and PDF downloads per browser and per IP address. The IP address is stored only as a salted hash, for two days. Server logs keep the usual request records for a short time.
Visits are counted with Vercel Web Analytics, which uses no cookies and does not follow you across sites; homie removes the identifier of a flat from the address before it is counted. homie also advertises on Google. Only if you accept advertising cookies in the cookie notice does the site load Google's ad tag (Google Ads), to learn whether a visit came from one of homie's ads; until then nothing is sent to Google for advertising. The addresses the tag sees never carry the identifier of a flat or the code of a link. You can change your answer at any time with “Cookie settings”.
If you send an estate agent a request link, the answers the agent gives, the documents they add and the name and email of the account they answer with are kept with the flat and shown to you. If you share your buyer profile link, whoever opens it sees the profile as you filled it in, and nothing else of your account.
Selling teams can put a flat's papers (a nota simple, plans, the ITE…) in its data room. homie keeps those files for the team, on its instructions, as its processor: the team decides who opens them, every buyer who opens one gets it stamped with their name and the day, and the team sees who opened what. The files are deleted when the team removes them, when the flat leaves its portfolio, or with the team.
homie on WhatsApp
When you write to homie on WhatsApp, homie stores your phone number, the messages you send and the replies it sends, and the flats you check there. The messages are kept for ninety days so a conversation can be followed, then deleted; delivery records are kept for thirty days.
Your messages travel through Meta's WhatsApp Business Platform and are read by a language model (Anthropic) to understand an address or a question and to write the reply. When you send a link to a listing on a property portal, homie opens that page once to read its price, size and address. Your number is never shown to anyone else, never sent to a register and never used to contact you about anything other than the flat you asked about.
The link homie sends you lets your own browser edit that flat. To show the report to someone else, use the second, plain link: it opens the report for reading only.
Why homie may use your data, and for how long
To give you the service you ask for (the flats you check, your account, what you add, the WhatsApp conversation), homie relies on providing that service to you (article 6.1.b of the GDPR). To keep it secure and within its limits, and to count visits without cookies, it relies on its legitimate interest in running a safe, working service (article 6.1.f). Advertising cookies rely only on your consent (article 6.1.a), which you can withdraw at any time.
Your flats and everything you add to them are kept until you remove them or ask homie to delete your account. WhatsApp messages, and questions to homie on the site with their answers, are kept for ninety days, and delivery records for thirty. Hashed IP addresses are kept for two days, server logs for a short time, and the record of what each answer cost for as long as the accounts require. Google's advertising cookies last up to ninety days, as the cookie section explains.
homie does not sell your data, does not use it to build a profile for advertising, and takes no decision about you with legal or similarly significant effects: its scores and findings are automatic readings of public data, shown to help you, and nothing is decided on them.
Your rights
You can ask homie for access to your data, to correct it, to delete it, to restrict or object to its use, and for a copy to take elsewhere (portability); and you can withdraw any consent you gave, without that affecting what was done before. Write to the privacy contact under Who runs homie; homie answers within one month. If you think your data is being mishandled, you can complain to the Spanish data protection authority (AEPD, aepd.es).
homie is meant for adults. If you are under eighteen, do not use it or send it your data.
The answers homie writes, on the site and on WhatsApp, are produced by an AI system (a language model). They can be wrong or incomplete: check anything important in the report and at its source.
Deleting your data
Removing a flat deletes its report and every fact, finding, plan, photo and document reading behind it.
On WhatsApp, send “delete my data”. homie asks you to confirm with the word DELETE and then erases everything it holds about your number: the conversation, the flats you checked there with everything attached to them, and the links it sent. It cannot be undone.
To close an account and delete everything it holds, or to ask for a copy of your data, use the contact under Who runs homie; during the trial, removing your flats and, on WhatsApp, “delete my data” erase what homie holds. You also have the right to complain to the Spanish data protection authority (AEPD, aepd.es).
Services homie relies on
Maps, Street View, aerial views, places nearby and the hourly air-quality snapshot come from Google. When a page shows a map, your browser talks to Google directly and Google's privacy policy applies to that traffic. Places and air quality are asked from homie's servers with the coordinates of the building only.
Sign-in, the database and the private photo storage run on Supabase. The site runs on Vercel, which also counts visits as described above.
Language models from Anthropic read floor plans, the redacted text of documents, questions asked on the site and WhatsApp messages, and write the answers. Anthropic does not use that content to train its models. WhatsApp messages are delivered by Meta.
Public registers are asked from homie's servers with the address or cadastral reference only. No account details are ever sent to them.
Google Ads measures homie's advertising, and only if you accept advertising cookies (see Cookies and browser storage).
Some of these providers (Google, Vercel, Anthropic and Meta, and Supabase for some services) are based in the United States or may process data outside the European Economic Area. Those transfers rely on the European Commission's adequacy decision for the EU-US Data Privacy Framework or on the standard contractual clauses the Commission approved.
Where the figures come from
Every figure in a report carries the register it came from and the moment it was pulled; the Sources tab of each flat lists the exact links. The institutions below publish that data under the terms linked here, and homie reuses it with attribution as they require. A register can be out of date or contain errors; homie shows what it says on the day, nothing more.

Their presence does not mean any of them checked, approved or endorse homie or its reports, and homie is not affiliated with any of them.

Terms of use
By using homie, on the site or on WhatsApp, you accept these terms. During its trial homie is free and offered as it is: it may change, pause or stop, and a limit may be lowered, without notice.
homie is an information tool. It is not an estate agency: it does not broker sales or lettings, charges no commission, and does not act for any buyer, seller, landlord, tenant or agent. It is not linked to the property portals whose listings you send it; a listing is read once, at your request, and belongs to its portal.
Use homie for your own search for a flat, or to help someone you know with theirs. Do not send addresses in bulk, copy reports out by machine, resell them, or work around the limits that keep the service within its budget, and do not send content that is unlawful or that belongs to someone else without their permission. homie may limit or refuse service to a browser, account or number that does.
To use homie you must be of legal age. Add only documents and photos you are entitled to share: homie removes personal details from documents before reading them, but you remain responsible for what you send.
A report is homie's reading of the public registers on the day it was pulled. homie does not promise it is complete, current or free of errors, and does not answer for decisions taken on it: check every figure that matters against the register itself before you sign anything. See Not advice below.
What you add stays yours: your plans, photos, documents and corrections. You let homie store and process them to build your report, and for nothing else; they are handled as described above.
Nothing in these terms limits any liability that Spanish law does not allow to be limited, such as for wilful misconduct or gross negligence, or your rights as a consumer.
Spanish law applies to these terms. Disputes go to the courts of Barcelona, unless consumer law gives you the courts where you live. If a part of these terms is found invalid, the rest stands.
Not advice
Everything homie shows is information to help you understand a flat and ask better questions. It is not legal, financial, tax, architectural or property advice, and it is not a recommendation to buy, rent, sell or sign.
Before you make an offer, sign a reservation or arras contract, apply for a mortgage or sign at the notary, check what matters with the right professional: a lawyer (the contract, charges, tenancies and planning), the Property Registry's nota simple (who owns the flat and what charges it carries), a notary, an architect or building surveyor (the state of the flat and the building), your bank, and a tax adviser or gestor (taxes and costs).
Estimated valuations, price comparisons, the room to negotiate, the scores and the verdict are homie's readings of public averages. None of them is a tasación: only an appraisal company approved by the Banco de España can issue the valuation a bank lends on (Orden ECO/805/2003). Figures such as taxes, mortgage costs and renovation bands are illustrations from public rates and typical prices, not quotes.
Public registers can be out of date or wrong, and homie can misread them. Check every figure that matters at its source. The decisions you take are yours.
