Welcome to Flock ("we," "our," or "us"). Your privacy matters to us. This Privacy Policy explains what information we collect, how we use it, and how we protect it.
1. Information We Collect
1.1 Account Information
When you create an account, we collect:
- Email address
- Password (stored in hashed form; we never store your plain-text password)
- Your name or nickname
1.2 Travel Profile
During onboarding and in your Profile, you provide:
- Your home city and the airports you fly from
- Whether you usually leave after work (used to filter departure times)
- Destinations you never want suggested
This data is used to run flight searches from your airports and to filter results. It is never sold.
1.3 Information About Your Friends
To plan a trip you enter, for each person travelling with you, a first name or nickname, the airports they fly from, and optionally their departure preferences and places they would rather skip. Your friends do not need an account and we do not contact them. This information is visible only to you, is used only to run your searches and to build your trip pages, and is deleted together with the trip or with your account.
Please only enter details about people who are happy for you to plan a trip with them. If a friend asks you to remove their details, you can edit or delete them from the trip at any time.
1.4 Searches and Results
When you run a search, we record:
- The dates or month you searched, and your options (direct flights only, flexible dates)
- The airports used for each participant at the time of the search
- The results returned: destinations, prices per person, airlines and times
- How many searches you have used this month
Results are stored so you can come back to them, share them, and lock a destination without searching again.
1.5 Trip Planning Data
As you plan, we store what you enter on a trip:
- The chosen destination and each participant's booking status
- Flight numbers you type in, which we use to look up scheduled departure and arrival times
- Accommodation links you save and the group's votes on them
- Activity ideas, notes and votes
- Shared expenses: description, amount, who paid and how it is split
1.6 Link Previews
When you save an accommodation link, our server fetches that web page once to read its public title, description and image so the App can show a preview card. We store only that preview, not the page.
1.7 Subscription Data
We record your subscription status through RevenueCat, our subscription management provider. Payment processing is handled entirely by Apple through the App Store. We do not store your credit card or payment details.
1.8 Usage Analytics
We collect anonymized usage data (for example which screens are opened, how many searches run, which sharing option is used) through PostHog, hosted in the European Union. Events are linked to a random account identifier, never to your email, name or your friends' names. We do not record screen contents or session replays.
2. How We Use Your Information
We use the information described above to:
- Run group flight searches from everyone's airports and rank the destinations
- Store your results so you can revisit, compare and share them
- Build the trip page: flights, booking status, accommodation, activities and expenses
- Look up scheduled times for the flight numbers you enter
- Calculate totals, per-person shares and who owes whom
- Enforce your monthly search allowance
- Keep your data in sync across your devices
- Improve the App through anonymized analytics
3. Data Sharing
We do not sell, rent, or share your personal data with third parties for marketing purposes.
We share data only with:
- Our flight data provider, which receives airport codes, dates and search options in order to return prices. It never receives your name, your email, or your friends' names.
- Service providers who help us operate the App (cloud hosting and authentication, subscription management, analytics), bound by confidentiality obligations and processing data only on our instructions.
- Apple, solely to process your subscription payment.
- Legal authorities if required by law or to protect the safety of our users.
When you share a shortlist or trip summary from the App, it is sent through the messaging app you choose, under that app's own privacy terms. We do not see where it goes.
4. Data Retention
Your account data is retained for as long as your account is active. If you delete your account, your profile, trips, participants, searches, accommodation, activities and expenses are permanently deleted, except where retention is required by law.
You can delete individual trips, participants, links, activities and expenses at any time within the App.
5. Your Rights
Depending on your location, you may have the right to:
- Access the personal data we hold about you
- Correct inaccurate data
- Request deletion of your data ("right to be forgotten")
- Export your data in a portable format
- Withdraw consent at any time
You can delete your account and all its data directly from the Profile screen in the App. For any other request, contact us at support@flock-travel.app.
6. Children's Privacy
Our App is intended for users aged 18 and older. We do not knowingly collect personal information from anyone under 18. If we become aware that a user under 18 has provided personal data, we will delete it promptly.
7. Data Security
We take the security of your data seriously. We use:
- Encrypted transmission (HTTPS/TLS) for all data in transit
- Hashed passwords; your password is never stored in plain text
- Secure cloud infrastructure hosted in the European Union, with access rules so that each account can only read its own data
- Regular security reviews
No system is 100% secure. If you believe your account has been compromised, please contact us immediately.
8. International Transfers
Your data is stored in the European Union. Some service providers, such as our flight data provider and Apple, may process limited data outside the EU. Where that happens we rely on their standard contractual safeguards.
9. Changes to This Policy
We may update this Privacy Policy from time to time. If we make material changes, we will notify you in the App or by email. Continued use of the App after changes are posted constitutes your acceptance of the updated policy.
