Privacy Policy

Last updated October 29, 2026

Planeology is an app for people who love aviation. This policy explains what information the app collects, why, who helps us process it, how long we keep it, and the choices you have.

Planeology is published by Kshitiz Sachan (“we”, “us”), who is responsible for the personal information described here. You can reach us through the support button in the app, or at support@planeology.app.

1What we collect

1.1 On your device only

Your lesson progress, quiz results, streaks, Hangar, settings, the name you give the app and your answers to its opening questions are stored on your device. Deleting the app deletes them. Your answers to the opening questions are also sent to our analytics (1.3).

1.2 Purchases

The App Store or Google Play handles payment for the Boarding Pass, so we never see your card or bank details. RevenueCat, the service that manages our in-app purchases, receives what you bought and whether your subscription is active, a random ID it creates for your copy of the app (your app ID), and basic device and app details such as the system version, app version and region. A new install gets a new app ID.

1.3 Analytics

We use PostHog to see how the app is used, so we can improve the lessons and features. It receives:

  • what you do in the app, such as onboarding steps, the plans you look at on the purchase screen (with their prices), lessons, quizzes, the daily challenge and rank-ups;
  • your answers to the opening questions and how you heard about Planeology;
  • whether you have a Boarding Pass;
  • a random install ID.

Your name isn’t sent. We set PostHog to discard IP addresses, so it doesn’t work out your location.

1.4 Crash reports

If the app crashes or slows down, Sentry receives a technical report: the device model, system and app versions, the error and where in the app it happened, and timings for a sample of sessions. Reports don’t include your name or app ID.

1.5 Notifications and our server

Daily reminders are scheduled on your device and don’t involve our server. Our server runs on Supabase, and the app sends it:

  • if you allow notifications: a push token for your device, your app ID, the platform and app version, your notification setting and your time zone, so we can send you announcements;
  • how you heard about Planeology with your time zone, and where a purchase started with the plan chosen, both kept only as running totals that aren’t linked to you;
  • if you cancel and choose to tell us why: the reason you type, your first name, your app ID, your time zone and the app version;
  • when the app opens: the platform (iOS or Android), to check whether a newer version exists.

Expo, which delivers our push notifications, receives your push token and the announcements we send.

1.6 Support chat

Each time you open the Home screen, AppSupportKit, our support chat service, receives your app ID, your first name (or “Anonymous”), whether you have a Boarding Pass or are on its free trial, the app version and your platform. This lets our team write to you first in the support chat, for example to ask how the app is working for you. Once you allow notifications, it also receives a push token so we can tell you about messages. When you open support, it receives the language you choose, and when you write to us, your message. Messages are translated automatically, so you and our team can each write in your own language. If you email us instead, we receive your email address and message and use them only to reply.

1.7 What we don’t collect

Planeology doesn’t collect your location, contacts, photos, health data, browsing history or advertising ID, and it doesn’t ask for an email address or an account.

2How we use it

We use this information to:

  • provide the app and the Boarding Pass, including restoring purchases;
  • answer your support requests;
  • send the notifications you’ve allowed;
  • see which lessons and features work, and improve them;
  • find and fix crashes;
  • understand where purchases start and why people cancel.

We don’t use your information for advertising, we don’t sell it, and we don’t share it with anyone for advertising. We don’t make automated decisions about you that have legal or similarly significant effects.

3Legal bases

If you’re in the European Economic Area, the UK or a country with similar law, we rely on these legal bases:

  • Contract: to sell, restore and check your Boarding Pass, and to answer your support requests.
  • Legitimate interests: analytics, crash reports, the running totals and cancellation feedback, which we need to run and improve the app. You can object at any time (section 6).
  • Consent: notifications. You can withdraw it at any time in your phone’s settings.
  • Legal obligation: keeping purchase records for tax and accounting.

4Who processes it

These services process information for us, only to provide their service and under their own security and privacy terms. Apple and Google also process payments under their own privacy policies.

ServiceWhat it does for us
RevenueCatManages purchases and subscription status
PostHogProduct analytics
SentryCrash and performance reports
SupabaseHosts our server and database, in the EU (Ireland)
AppSupportKitIn-app support chat, including message translation
ExpoDelivers push notifications

5How long we keep it

InformationKept for
On your deviceUntil you delete the app
AnalyticsUp to 24 months
Crash reportsUp to 90 days
Support conversationsUp to 24 months after your last message
Cancellation feedbackUp to 24 months
Push and device recordsDeleted after 12 months without use
Running totalsKept, since they contain no personal information
Purchase recordsAs long as tax and accounting law requires

When you ask us to delete your information, we do so sooner, unless the law requires us to keep it.

6Your choices and rights

Choices

  • Turn notifications off at any time in your phone’s settings.
  • Support chat and cancellation feedback are optional.
  • Deleting the app removes everything stored on your device.

Rights

Depending on where you live, you can ask us to give you a copy of your information, correct it or delete it, and you can object to or limit how we use it. California residents and those of some other US states also have the right to know what we collect, and not to be treated differently for using these rights. We don’t sell or share personal information as those laws define it.

How to ask

Use the support button in the app. Your request then comes with your app ID, which is how we find information linked to you, since Planeology has no accounts. You can also email support@planeology.app, but we may ask you to send the request from the app so we can find your information. We reply within 30 days.

Analytics use a random install ID that isn’t linked to your app ID, so we can’t pick out your analytics data. It is deleted when its retention period ends.

If you’re in the EEA or the UK, you can also complain to your local data protection authority.

7Children

Planeology is for a general audience. It isn’t directed at children under 13, and we don’t knowingly collect personal information from them. If you believe a child has sent us personal information, for example through support chat, contact us and we’ll delete it.

8Security

Everything the app sends travels over encrypted connections (HTTPS). Only the people who run Planeology can access our services, and our providers protect the information they hold. No system is perfectly secure, but we work to keep your information safe.

9International transfers

Our providers may process information in the United States, the European Union and other countries. Where the law requires it, these transfers are protected by safeguards such as the European Commission’s Standard Contractual Clauses.

10This website

This website doesn’t use cookies, analytics or ads, and it loads nothing from other companies. Like any website, our hosting provider may keep standard server logs, such as IP addresses, for a short time for security.

11Changes to this policy

If we change this policy, we’ll update this page and the date at the top. If a change is significant, we’ll also tell you in the app before it takes effect.
