🔑 Spare Keys Stay

Privacy Policy

Effective date: July 27, 2026 · Last updated: October 27, 2026

Spare Keys Stay respects your privacy. This Privacy Policy explains what information we collect, how we use it, and the choices available to you when you visit SpareKeysStay.com, submit an inquiry, or request or complete a reservation.

Information We Collect

We may collect information that you provide directly to us, including:

We may also collect certain technical information automatically, including your browser type, device type, approximate location, IP address, pages visited, referring website, advertising interactions and activity on our website.

Site Activity and Feedback

To understand and improve our website, we record the steps visitors take on it — such as the pages and apartments viewed, photos browsed, dates searched and booking steps — along with device type and screen size. We may review these steps later, including by playing them back in order, to see where our website is hard to use. These records do not include anything you type into forms.

Before you leave, we may ask one short optional question about your visit. If you answer, we keep your answer. If you choose to give us your email there, we use it only to send what you asked for, such as a special offer or a note when your dates become available.

Trip Assistant

Our trip assistant at sparekeysstay.com/boston/ answers questions about a Boston visit and our apartments. What you type or say there is sent to Anthropic, the maker of the Claude AI model, to write the answer; the dates and group size are sent to our booking system (Hospitable) to check live availability and prices. If you turn on spoken answers, the answer’s text is sent to Google to be read aloud, and if you use the microphone, your browser’s or phone’s own speech recognition turns your voice into text. The assistant does not ask for your name, email or phone number, and we do not keep the questions you ask; Anthropic and Google process them under their own privacy terms. The conversation stays only in your browser tab, so it is still there if you go back to it from one of our pages; it is cleared after 12 hours, when you reload or open the page again, or when you close the tab.

AI assistants and apps, such as ChatGPT or Claude, can look up our apartments at sparekeysstay.com/api/ai-inventory, or through our connector for AI assistants at sparekeysstay.com/mcp (the Model Context Protocol), which uses the same search and gives a booking link with the dates filled in. A search there carries only what the assistant asks about — dates, number of guests, trip type, neighborhood or a place to be near — never a name, email address or phone number. The dates and group size are sent to our booking system (Hospitable) to check live availability and prices. We keep a record of each search (what was asked, the assistant’s name as its software reports it, the approximate city it came from and how many apartments were open) to see how assistants use it. The assistant you use handles your conversation under its own privacy terms; nothing is booked or paid for until you book on our website yourself.

Giveaways

When you enter one of our giveaways at sparekeysstay.com/giveaway/, we collect your first and last name, email address, phone number if you give one, country and state, province or town, and, if you add them, your trip dates and group size. We also record which ad or website brought you there, your share code and the share code you arrived with, and a scrambled marker made from your internet address (not the address itself) so one household cannot enter many times.

We use this to run the drawing, count bonus entries, prevent duplicate or automated entries, and contact the winner. If you win, we publish your first name, last initial and state or country as the Official Rules describe. We email you deals only if you tick the separate optional box, and every such email lets you stop them. If you add trip dates, they are sent to our booking system (Hospitable) to show which apartments are open, the same way our booking box does.

We keep giveaway entries for up to 12 months after the drawing, then delete them. If you agreed to receive deals, we keep your name and email for that until you unsubscribe or ask us to delete them. We never sell entry information.

Entries are stored and processed in the United States. For entrants in the UK and Ireland, we run the drawing to perform the Official Rules you accept, we prevent duplicate and automated entries because we have a legitimate interest in a fair drawing, and we send deals only with your consent, which you can withdraw at any time. You can ask to see, correct or delete your entry by emailing dcreese@sparekeysstay.com, and you may complain to your data protection authority.

How We Use Your Information

We may use your information to:

Reservations and Hospitable

Our availability calendar, reservation process, guest communications and certain payment-related services may be provided through Hospitable or its associated service providers. When you use these booking services, your information may be collected and processed according to Hospitable’s applicable privacy policy and terms. Spare Keys Stay does not directly store complete payment-card details processed by our payment providers.

Analytics, Advertising and Remarketing

We use Google Analytics, Google Ads, Google Tag Manager and related services to understand how visitors use our website, measure advertising results and advertise online. Third-party vendors, including Google, show our ads on sites across the internet and use cookies and/or device identifiers to serve ads based on your past visits to our website. Google may process this information according to its own privacy policies.

You can opt out of Google's use of cookies or device identifiers for personalized ads by visiting Google's Ads Settings (adssettings.google.com), opt out of third-party vendors' use of cookies for personalized advertising by visiting the Network Advertising Initiative opt-out page (optout.networkadvertising.org) or the Digital Advertising Alliance opt-out page (optout.aboutads.info), or control the use of device identifiers by using your device's settings.

When you book directly with us after clicking one of our Google ads, we share a scrambled (SHA-256 hashed) copy of the email address and phone number on your booking with Google, together with the booking amount and a reference to the ad click, so that Google can perform ad measurement services on our behalf — telling us whether our ads led to bookings. Google’s tag on our booking pages may also send a scrambled copy of the email address and phone number you enter in our booking form, for the same purpose. Google receives only the scrambled copy, never your email address or phone number as written. We do not share it from our booking records if your browser sends a Global Privacy Control signal, or if you visited our website from the European Economic Area, the United Kingdom or Switzerland; when your browser sends a Global Privacy Control signal, or you visit from the European Economic Area, the United Kingdom or Switzerland, our Google tag is also told not to use your data for advertising.

You can learn more about how Google uses information from participating websites at: https://policies.google.com/technologies/partner-sites

We also use Microsoft Advertising’s Universal Event Tracking (UET) to measure our ads on Bing, MSN and Microsoft Edge — for example, whether someone who clicked one of our Microsoft ads went on to check prices for their dates. Through UET, Microsoft collects or receives personal data from visitors (using cookies or similar technologies) to provide Microsoft Advertising, and handles that information according to the Microsoft Privacy Statement. You can opt out of personalized advertising from Microsoft at account.microsoft.com/privacy/ad-settings. When your browser sends a Global Privacy Control signal, or its time zone is set to Europe, our Microsoft tag is told not to store advertising data.

Cookies and Similar Technologies

Our website and service providers may use cookies and similar technologies for:

Where legally required, visitors will be offered choices regarding nonessential cookies. You may also control cookies through your browser settings. Disabling certain cookies may affect website or booking functionality.

How We Share Information

We do not sell your personal information.

We may share information with service providers that help us operate the website and provide accommodations, including booking, payment, communications, website hosting, analytics, advertising, fraud prevention and customer-support providers.

We may also disclose information when required by law, to protect our legal rights or to prevent fraud, abuse or safety threats.

Data Retention

We retain personal information only for as long as reasonably necessary to provide our services, maintain business and reservation records, resolve disputes, enforce agreements and comply with legal obligations.

Your Choices

You may contact us to request access to, correction of or deletion of personal information that we maintain about you, subject to applicable legal and recordkeeping requirements.

You may unsubscribe from promotional emails by using the unsubscribe instructions in those messages. Reservation-related and service communications may still be sent when necessary.

Data Security

We use reasonable administrative and technical measures intended to protect personal information. However, no website, electronic transmission or storage system can be guaranteed to be completely secure.

Children’s Privacy

Our website and accommodation services are not directed toward children under 13, and we do not knowingly collect personal information directly from children under 13.

Changes to This Policy

We may update this Privacy Policy periodically. Changes will be posted on this page with an updated date.
