✦ hangpalprivacy policy
last updated: july 25, 2026
hangpal is a small, independent project built by one person, not a company with a data department. this page covers everything: joining the waitlist, signing in, connecting a calendar, chatting with the agent, and paying for it. it's written to be read, not to hide anything. if anything here is unclear, email us, a real person answers. see also the terms of service.
the short version
- we don't sell your data, ever, to anyone.
- your calendar is read-only. hangpal never creates, edits, or deletes events (aside from creating an importable calendar event file).
- your friends' names and hangout history stay inside your account, never shown to anyone else and never used to train big AI models.
- you can disconnect your calendar, export your data, or delete your account at any time (just email us to do the last two).
what we collect
if you're on the waitlist
- your email address. that's the only thing we ask for to join the waitlist.
- basic technical info. like most sites, our host logs the standard things your browser sends: rough city-level location, device and browser type, and the page you came from.
- ad and analytics signals. if you arrived from one of our ads, tools like the Meta pixel may set cookies so we can tell the ad worked. they don't tell us who you are by name.
once you sign in
- your Google account basics. name, email address, and profile photo, from signing in with Google.
- your calendar, read-only. if you connect Google Calendar (or paste an Apple/Outlook ICS link), hangpal reads event titles, times, and attendees to figure out who you've hung out with and when you're free. it never writes, edits, or deletes anything on your calendar. calendar access tokens are encrypted at rest.
- your friends roster. names, how you know them, notes you add, and how recently you've seen them, whether entered by hand or inferred from your calendar.
- hangout history. dates, activities, locations, and notes for hangouts you log or the agent identifies from your calendar.
- your chat messages. what you say to the hangpal agent, and its replies, so it has context across a conversation and can pick up where you left off.
- your home city and rough coordinates. used to check the weather and suggest nearby things to do; never a precise location.
- saved ideas and preferences. plans you've saved, dashboard suggestions you've interacted with, and settings like your digest email preference.
- usage and cost logs. which features you use and how much the AI behind the scenes costs to run for your account. this is for keeping the service healthy and affordable, not for profiling you.
- payment information, if you subscribe. hangpal never sees or stores your card number. Stripe, our payment processor, handles that directly; we only keep a customer/subscription reference and your billing status.
how we use it
- to run the actual product: draft invite texts, suggest who you've been drifting from, find local things to do, and remember your friends and past hangouts.
- to check calendar availability when planning something with a friend.
- to send you the weekly digest, if you've opted in, and account or billing emails you need (like a receipt or a payment failure notice).
- to email you when your invite off the waitlist is ready, plus the occasional short note about the launch.
- to measure whether our ads are reaching the right people.
- to keep the service secure, spam-free, and within the usage limits that keep it affordable to run.
that's the whole list. we don't use your information for anything you didn't sign up for.
google user data
hangpal's use and transfer of information received from Google APIs adheres to the Google API Services User Data Policy, including the Limited Use requirements. concretely: calendar data is used only to power the features described above, inside your own account. it is never sold, never shown to other users, never used for advertising, and never used to train big AI or machine-learning models, ours or anyone else's. you can revoke hangpal's calendar access at any time from your Google account permissions or from hangpal's settings page.
who we share it with
we don't sell your data. ever. we rely on a small set of trusted services to operate hangpal, each of which only handles what it needs to do its job:
- Vercel and Neon, hosting and our database.
- Google, sign-in and calendar access, on your explicit consent.
- Anthropic, powers the AI agent; your chat messages and the roster/calendar context needed to answer you are sent to Anthropic's Claude models to generate a response.
- Tavily, web search the agent uses to find local events and activities.
- Resend, sends transactional email (digests, invites, billing notices).
- Stripe, processes payments if you subscribe; handles your card details directly, we never see them.
- Sentry, error monitoring, so we can catch and fix bugs. it's configured not to capture personal data or session recordings.
- Meta, ad measurement for people who arrive from one of our ads.
how long we keep it
while you're on the waitlist, we hold your email until launch, plus a reasonable window after, so we can invite people in waves. once you have an account, we keep your data for as long as the account is active. if you delete your account, we delete your friends, hangouts, chat history, and calendar tokens; a minimal record (like billing history) may be kept as long as the law requires. ask us to delete anything at any point and we will, no questions asked.
your choices
- disconnect your calendar any time from settings, or by revoking access in your Google account.
- unsubscribe from any email using the link at the bottom of it.
- see, export, correct, or delete anything we hold by emailing us.
- cancel a subscription any time from the billing portal in settings.
- opt out of ad tracking through your browser, device settings, or your Meta ad preferences.
security
calendar access tokens are encrypted at rest, not stored in plain text. all traffic to and from hangpal is encrypted in transit.
housekeeping
hangpal isn't meant for anyone under 16, and we don't knowingly collect their information. if this policy changes, we'll update the date above. material changes will be obvious, and if you have an account we'll email you about anything that changes how your data is used.
contact
questions, or want your data gone? email hello@hangpal.app and a real person (hi) will answer.
accessibility
hangpal aims to meet WCAG 2.1 AA guidelines. if you run into a color, contrast, keyboard, or screen-reader issue anywhere in the app, or need something in a different format, email hello@hangpal.app and tell us what you were doing. we'll fix it or find a workaround, and you'll hear back soon.
