Privacy Policy

Last Updated:
August 12, 2026

This policy explains what StationScope collects when you use the Service, why it collects it, who it is shared with, how long it is kept, and what you can ask StationScope to do with it. StationScope is a small independent product operated from the United States for renters in seven United States metropolitan areas. This policy describes what the Service does today, not what it might do in the future. If a practice changes, this policy will be updated and the date above will change with it.

1.Definitions

Service.
the StationScope website, applications, and recommendation tools (Tandem mode and Solo mode).
Personal Information.
information that identifies, relates to, or could reasonably be linked with you, including email address, the first name you may supply in Tandem mode, the address you type into the address box, and chat content you submit.
Tandem Group.
a set of two to five users using Tandem mode jointly to produce a shared neighborhood recommendation.

2.Information StationScope Collects

StationScope has no user accounts and no passwords. Everything below is collected because you typed it, because you paid for something, or because your browser sent it with the request.

  • Tandem Mode. StationScope collects your email address, the first name you enter when you join a group (used only as a display label next to your contributions), chat responses (housing preferences, location constraints, lifestyle factors), the address you enter and the map coordinates it resolves to, city and neighborhood preferences, and group composition (number of members, relationship type, bedroom count, whether children are part of the household and their ages if you say so, and optionally MBTI personality types). Your email address is the join key for the group; the name is a label only.
  • Solo Mode. StationScope collects the address you enter for station search, the map coordinates and nearest station it resolves to, any preferences you submit during the session, and the resulting chat transcript. Solo mode has no sign-in: a session identifier generated in your browser tab is the only link between your turns. If you buy Refine Further, the email address you give Stripe at checkout is also stored so the report can be sent to you.
  • Payment Information. Card data is entered on a checkout page hosted by Stripe and is handled entirely by Stripe. StationScope never sees, receives, or stores full card numbers, security codes, or expiry dates. What StationScope stores is the Stripe checkout session identifier, whether the payment succeeded, the email address you gave Stripe, and the access code minted for that purchase.
  • Technical and Usage Information. When you send a chat message, StationScope records your IP address, browser user agent, language preference, referring page, any campaign parameters in the link you arrived through, and any Do Not Track or Global Privacy Control signal your browser sent, alongside the saved transcript. StationScope also records the number of tokens each recommendation consumed, with no user identity attached, so it can track its own running costs.

3.Information StationScope Does Not Collect

Some categories are deliberately out of scope. StationScope does not ask for the following, and its chat is instructed not to probe for them.

  • Income, salary, employment status, or credit history. The chat asks what you are willing to spend on rent, which is a budget figure you choose. It does not ask what you earn, who in your household earns more, or whether anyone is employed. If you volunteer that kind of detail, the chat is instructed to accept it and move on rather than follow up on it.
  • Social Security numbers, government identification numbers, driver's license numbers, or financial account numbers.
  • Protected-class characteristics as selection criteria. StationScope does not ask your race, color, religion, national origin, sex, familial status, or disability, and does not use any such characteristic to include or exclude a neighborhood. If you raise one of these topics in chat, the chat is instructed to decline the demographic question and redirect to the concrete feature you are likely asking about.
  • Full payment card numbers, security codes, or expiry dates. These go to Stripe and never reach StationScope.
  • Device GPS location. StationScope works from the address you type, not from your device's location sensor, and does not request location permission from your browser.

4.How StationScope Uses Information

  • To generate neighborhood recommendations through large language models (currently the Anthropic Claude API).
  • To deliver recommendation reports by email (through Resend).
  • To store group data and chat transcripts on Supabase, so that multi-member Tandem flows can associate members with the same group and so that Solo and Tandem chats can be resumed.
  • To take payment, confirm it succeeded, issue the access code or unlock that the payment bought, and answer billing questions later.
  • To answer support messages you send, and to investigate a problem you report.
  • To measure aggregate website usage through Google Analytics, and to monitor the Service's own running costs and error rates.
  • To review how the recommendation pipeline is performing and improve its quality, including reading stored transcripts when diagnosing a defect.
  • To protect the Service against abuse, fraud, and chargeback disputes, and to comply with legal obligations or lawful requests.

StationScope does not sell your Personal Information, does not rent or trade it, and does not share it for cross-context behavioral advertising.

5.Scope and Legal Bases

The Service covers seven United States metropolitan areas, is offered to users in the United States, and is not directed at or marketed to residents of the European Economic Area, the United Kingdom, or Switzerland. StationScope does not claim to operate a full European data protection compliance program.

Where a data protection law that requires a legal basis does apply to you, StationScope relies on the following: performance of a contract, for the processing needed to produce and deliver the recommendation you asked for and to take payment; legitimate interests, for security, fraud prevention, cost monitoring, quality review, and aggregate usage measurement; consent, where you volunteer information the Service did not ask for; and legal obligation, where StationScope must retain or disclose records.

6.Third-Party Processors

StationScope engages the following third-party processors. Each receives only what its function requires, and each is governed by its own terms and privacy policy. StationScope does not control how these companies operate their own systems.

Anthropic.
AI processing of chat content; receives your chat messages and the group or session context needed to produce a recommendation.
Resend.
transactional email delivery; receives your email address and the rendered report or notification.
Stripe.
payment processing; hosts the checkout page and handles all card data. StationScope receives back only a session identifier, the payment status, and the email address you entered at checkout.
Supabase.
database; stores StationScope's group, member, recommendation, payment-unlock, and chat transcript records.
Railway.
hosting; runs the StationScope website and its backend, and therefore processes every request you make to the Service, including your IP address.
LocationIQ.
geocoding and address autocomplete; when you type an address, StationScope's server sends that text to return matching suggestions. Receives the partial address query and the map region of the city you selected. Map data © OpenStreetMap contributors.
OpenFreeMap.
interactive map tiles; the map in your browser loads base map tiles directly from OpenFreeMap, which therefore receives your IP address and the map areas you view (standard for any web map). No account, key, or cookie is involved. Map data © OpenStreetMap contributors.
Geoapify.
map images in emailed reports; StationScope's servers load base map tiles from Geoapify when composing the static map image in your report email. No data about you is sent; the request comes from StationScope's servers. Map data © OpenStreetMap contributors.
Google Analytics.
website usage analytics; receives your IP address, the pages you visit, and standard browser and device information, and sets cookies. StationScope uses this only to understand aggregate site usage.

StationScope may also disclose information to its professional advisers, to a successor in the event the Service is sold or transferred, or where required by law, subpoena, or a good-faith belief that disclosure is necessary to protect rights or safety.

7.Public Data Sources

The following are sources StationScope reads from, not processors it sends your information to. No user data is transmitted to any of them.

United States Census Bureau (ACS 5-year estimates).
public demographic and rent data by census tract, queried through the Bureau's public API. This product uses the Census Bureau Data API but is not endorsed or certified by the Census Bureau.
Transit agencies.
station names, routes, and coordinates derived from schedule data (GTFS feeds) published by the transit agencies serving each metropolitan area. StationScope is not affiliated with, endorsed by, or sponsored by any of them.

8.Cookies, Browser Storage, and Analytics

Every page of the Service loads Google Analytics 4, which sets its own cookies in your browser and reports your IP address, the pages you view, and standard browser and device information to Google. StationScope uses it only to see aggregate traffic patterns. It runs on page load rather than after a consent click: the notice at the bottom of the screen informs you that analytics cookies are in use and links to this policy, and it is a notice rather than a consent gate. If you want to prevent Google Analytics from running, use a browser or extension that blocks it, or Google's own opt-out add-on.

The Service also uses your browser's own session and local storage to remember things like your current chat session identifier, your language choice, and whether you have dismissed the cookie notice. That data stays in your browser and is not itself sent to StationScope, though the session identifier accompanies your chat requests so the conversation can continue.

If your browser sends a Do Not Track or Global Privacy Control signal, StationScope records that signal alongside the session so those sessions can be filtered out of its own analysis. That signal does not currently stop Google Analytics from loading, and StationScope does not otherwise represent that it honors Do Not Track.

9.What StationScope Does Not Do

  • StationScope does not operate advertising trackers and does not use your information for advertising or ad targeting. StationScope uses Google Analytics solely to measure aggregate website usage (see Cookies, Browser Storage, and Analytics).
  • StationScope does not share your individual chat content with other members of your Tandem Group beyond what the final recommendation report presents. The report aggregates each member's preferences into compromise findings rather than republishing them verbatim, and anonymizes content where reasonably practicable. Because the report is written for the whole group, do not enter anything in a Tandem chat that you would not want summarized to the people you plan to live with.
  • StationScope does not sell your Personal Information and has never sold it.

10.Data Retention

StationScope does not currently run an automated schedule that deletes old records on a fixed timetable. Records are kept while they remain useful for the purposes described above and are deleted on request or when StationScope no longer needs them. Payment and access-code records are kept longer than chat data, because they are the evidence behind a purchase and may be needed for accounting, tax, or dispute handling.

Tandem Group data and chat transcripts are retained while the group is active and for a reasonable period thereafter in order to support follow-up inquiries. To request deletion, contact stationscope@gmail.com.

Solo session data, including the chat transcript, the address you enter, the resolved map coordinates, and your IP address, is stored on Supabase. It is retained for a reasonable period to operate the session, allow you to resume a chat, and improve the service. To request deletion, use the contact address above.

Copies held by the processors listed above, such as email delivery logs at Resend or payment records at Stripe, are kept under those companies' own retention schedules, which StationScope does not control.

11.Your Rights

Subject to applicable law, you may exercise certain rights over your Personal Information by contacting StationScope at the address in the Contact section below. You have the right of access, meaning you may request a copy of the Personal Information StationScope holds about you; the right of correction, meaning you may ask StationScope to fix information that is inaccurate; and the right of deletion, meaning you may request that StationScope delete the Personal Information it holds about you, subject to legitimate retention obligations.

Requests are handled by a person reading email, not by a self-service dashboard: there is no account page where you can delete your own data. Send your request to the contact address and describe what you used (Tandem or Solo), the email address involved, and the approximate date, so the right records can be found. StationScope may need to ask a follow-up question to confirm the request comes from you, and may decline a request it cannot verify or that would require deleting another group member's records.

Residents of California and of other states with comprehensive privacy statutes may have additional rights, including the right to know the categories of information collected and disclosed, the right to delete, the right to correct, and the right not to be discriminated against for exercising those rights. StationScope does not sell Personal Information or share it for cross-context behavioral advertising, so there is nothing to opt out of on that front. Use the same contact address to exercise any of these rights.

12.Data Security

StationScope takes reasonable measures to protect the information it holds. Traffic to the Service travels over encrypted connections, the database sits behind row-level access rules, payment card data never touches StationScope's own systems, and access to production data is limited to the operator. No system is perfectly secure, and StationScope cannot guarantee that its safeguards or those of its processors will never fail. You use the Service with that understanding. If StationScope becomes aware of a breach affecting your Personal Information, it will notify affected users as required by applicable law.

13.International Users and Data Transfers

StationScope is operated from the United States and its processors store and process data in the United States and, in some cases, in other countries where those companies operate. If you access the Service from outside the United States, you are sending your information to the United States, where privacy laws may differ from those of your own country, and you consent to that transfer by using the Service. The Service itself only covers United States metropolitan areas, so it is unlikely to be useful outside them.

14.Children's Privacy

The Service is intended for adults aged 18 or older who are searching for a rental, and it is not directed to children. StationScope does not knowingly collect Personal Information from anyone under 13, and does not knowingly collect it from anyone under 18. If you are a parent or guardian and believe a child has provided StationScope with Personal Information, contact StationScope and it will be deleted. Note that a parent describing their household in Tandem mode may mention the number and ages of their children; that is information the parent supplies about the household, and the children themselves are not users of the Service.

15.Changes to This Policy

StationScope may update this policy as the Service changes. When it does, the date at the top of this page will be updated, and the current version will always be posted here. If a change materially reduces the protection given to information already collected, StationScope will make a reasonable effort to give notice on the site before it takes effect. Continued use of the Service after an update means you accept the updated policy.

16.Contact

Questions regarding this Privacy Policy, and requests to access, correct, or delete your information, may be directed to stationscope@gmail.com. This is the only contact channel StationScope monitors.
