Hound-Up is a business management app for solo dog walkers — scheduling, client and dog records, and invoicing. It's built to work entirely offline. This page explains, plainly, what data the app handles and where it goes.
Everything you enter — client details, dog details, schedules, walk records, notes, and invoices — is stored locally on your device using Apple's on-device database (SwiftData). Andy Vaughan has no server that stores or has access to this data.
If you turn on iCloud sync in Settings, this same data is also stored in your own private iCloud account, using Apple's CloudKit, so it carries over to your other devices. This sync is between your device and Apple directly — Andy Vaughan cannot see, access, or receive this data at any point. Apple's own privacy policy governs how iCloud handles it.
When you choose to email an invoice from inside the app, the following is sent, only for that purpose, to a backend that relays it on to your client:
This is relayed through two services, solely to deliver that one email:
Supabase — runs the backend that receives the request and forwards it to Resend. It also stores a device attestation key for your phone (see below), so the sending feature can't be abused by requests that didn't come from a genuine copy of the app. This key isn't linked to your name, your clients, or any account — there are no accounts.
Resend — the email delivery provider that actually sends the message to your client's inbox.
None of this is stored for any purpose beyond delivering that email, used for marketing, or sold or shared with anyone else. If you never use the "email invoice" feature, none of this ever happens — you can also just print or share invoices directly from your device instead.
Before the app can email an invoice, Apple's App Attest generates a one-time cryptographic key for your device and confirms with Apple that it's a genuine, untampered copy of Hound-Up. This is a standard anti-abuse mechanism — it identifies your device, not you, and carries no personal information.
If you use voice-to-text for walk notes, the audio is transcribed entirely on your device using Apple's on-device Speech framework. Nothing is recorded, stored, or sent anywhere.
Hound-Up is a tool you use to run your own dog-walking business. The personal details you enter about your clients (names, addresses, contact details, emergency contacts, and their dogs' medical/vet information) are your responsibility to collect and use appropriately — for example, telling clients you keep these records and only using them for the purposes they'd reasonably expect (scheduling and invoicing their walks).
You can edit or delete any client, dog, or walk record at any time from within the app. Deleting the app from your device removes the local copy; if iCloud sync was on, you can also delete the data from iCloud in the app or via your device's iCloud settings.
Hound-Up isn't directed at children and isn't intended for use by them.
