What's On is a privacy-first email-triage app for iPhone and Mac, provided by Chapple Property Services Ltd (“we”, “us”, “What's On”), a company registered in England & Wales, operated by Oliver Chapple. Registered office: 7-8 Crescent Stables, 139 Upper Richmond Road, London, SW15 2TN.
For any privacy question or to exercise your rights, contact us at ollierc@gmail.com. We are the data controller for the personal data described below, except where stated otherwise (see §4 — for the Private plan you act as controller of your own Anthropic API usage).
What's On reads your mail and maintains a prioritised task board. The AI never runs on our servers. It runs in one of two places depending on your plan, and this changes who can see your email content:
Your mailbox connections and, on the Private plan, your Anthropic API key are held on your device. We do not receive them.
To sync your board across devices and run the Connected routine, we store the following email-derived personal data:
Purchases and subscriptions are processed by Apple via the App Store; we receive confirmation of your subscription status but not your payment details. While the app is in TestFlight, Apple also collects standard crash and beta-usage data. We use no third-party analytics, advertising or tracking SDKs of any kind. Our relay keeps ordinary server logs (e.g. IP address, timestamps) for security and reliability.
Because the AI runs in your own Anthropic environment, Anthropic's data policies apply to the processing of your email content, and they differ by plan:
| Connected (your Claude Pro/Max) | Private (your API key) | |
|---|---|---|
| Governed by | Anthropic Consumer Terms | Anthropic Commercial / API Terms |
| Used to train models? | Only if you leave training on — see below | No — API data is not used for training |
| Typical retention at Anthropic | Up to 5 years if training on; ~30 days if opted out | Short abuse-monitoring window only (days) |
We are not affiliated with or endorsed by Anthropic. Your use of Claude or the Anthropic API is also governed by Anthropic's own terms and privacy policy.
Your board, memory and routine data are stored on our relay server hosted in Germany (EU) by Hetzner Online GmbH. We protect it with access controls and encryption in transit (TLS).
We never sell your personal data and we serve no advertising.
If your subscription lapses, we keep your data bucket for up to 6 months from your last activity so that resubscribing resumes your board instantly with no re-onboarding. After that it is automatically deleted. You can ask us to delete your data immediately at any time (see §10).
Account and transaction records may be kept longer where we are legally required to retain them.
We share the minimum necessary with the following, each under their own terms:
| Provider | Purpose | Data involved |
|---|---|---|
| Apple | App distribution, in-app purchases, TestFlight, push (if enabled) | Subscription status, crash/beta data |
| Anthropic | The AI triage (your Claude plan or your API key) | Email content processed in your own Anthropic environment |
| Google / Microsoft | Gmail and Microsoft 365 mailbox access you authorise | Mailbox access via OAuth (held on device / in connectors) |
| Hetzner Online GmbH | Relay & database hosting (Germany, EU) | Your stored board, memory, routine data |
| Resend, Inc. (United States) | Sending setup & restore emails | Your email address, setup links |
We do not sell data or share it with advertisers or data brokers.
Your relay data is stored in the EU (Germany). Some subprocessors (e.g. Apple, Anthropic) may process data outside the UK/EU. Where they do, transfers are protected by appropriate safeguards such as the UK International Data Transfer Agreement, the EU Standard Contractual Clauses, or an adequacy decision.
Subject to applicable law, you have the right to access, correct, delete, restrict, object to, or port your personal data, and to withdraw consent. To exercise any of these — including immediate deletion of your stored bucket — email ollierc@gmail.com. We will respond within the timeframes required by law (generally one month).
UK/EU residents: you may complain to a supervisory authority — in the UK, the Information Commissioner's Office (ICO), ico.org.uk.
California residents (CCPA/CPRA): you have the right to know, delete, correct, and opt out of “sale” or “sharing” of personal information. We do not sell or share your personal information as those terms are defined, and we do not discriminate against you for exercising your rights.
What's On is not intended for, and may not be used by, anyone under 16. We do not knowingly collect data from children under 16. If you believe a child has provided us data, contact us and we will delete it.
We may update this policy as the app evolves (for example, when we add end-to-end encryption or change subprocessors). We will post the new version here with an updated date and, for material changes, notify you in-app.
Questions, requests or complaints: Chapple Property Services Ltd, ollierc@gmail.com. We aim to resolve concerns directly; you also have the right to complain to your data protection authority (see §10).
