In short: Stub is built local-first. Your invoices, clients, business details and logo stay on your device. There is no account to create, we do not run ads or third-party analytics, and we never sell your data.
This policy explains how Stub ("Stub", "we", "us") handles information when you use the Stub app. Stub is provided by the developer identified for Stub in the App Store listing.
Everything you enter into Stub — business profile, logo, clients, invoices, line items and generated PDFs — is stored locally on your device. We do not have a server that receives or stores this content, and we cannot see it. If you enable Apple's device backup or iCloud backup, a copy of your app data may be included in that backup under your own Apple account and Apple's terms; that is controlled by you and Apple, not by us.
If you unlock Premium, Stub can sync your app data across your own devices using Apple's iCloud (CloudKit). Your data is stored in your own private iCloud database under your Apple account — it never reaches a server of ours, and we cannot access it. Syncing is handled entirely by Apple under your Apple account and Apple's terms. You can turn it off by not using Premium or by managing iCloud in your device settings.
Premium features are sold as in-app purchases. Payments are processed by Apple through the App Store — we never receive your card or payment details. To unlock and restore premium across your devices we use RevenueCat, which processes a randomly generated app user identifier together with purchase history and receipt information needed to validate your entitlement, prevent fraud, and restore purchases. We do not use this purchase information for tracking or advertising, and we do not receive your card number, billing address, Apple ID, name, or email from Apple or RevenueCat. See RevenueCat's Privacy Policy and Apple's Privacy Policy for how they handle that data.
When you send or share an invoice PDF, it is handed to the destination you choose (Mail, Messages, Files, AirDrop, etc.) through the system share sheet. That sharing happens directly from your device under your control; the PDF does not pass through us.
We require service providers we use for app functionality to handle data consistently with this policy and applicable privacy requirements. We use no other third-party services to collect data about you.
Because your data lives on your device, you are in control of it. You can delete individual invoices and clients in the app, and deleting the app removes all of its local data from your device. Purchase records held by Apple and RevenueCat are retained according to their respective policies and legal obligations.
You can review, edit, export by sharing, or delete the invoice information stored in Stub using the app and iOS system features. You may also contact us to ask questions or request access, correction, deletion, restriction, or objection where those rights apply in your location. Because invoice content is stored only on your device, we may not be able to access or recover it for you. For App Store purchases, subscription management, refunds, and Apple account records, please use your Apple Account settings or Apple support. For RevenueCat entitlement records, contact us and we will help route the request where possible.
Your content is stored within the app's protected, sandboxed storage on your device and benefits from the device's own security (passcode/biometric and disk encryption). Network requests for purchase validation use encrypted (HTTPS) connections.
Stub is a business tool intended for adults and is not directed to children. We do not knowingly collect personal information from children.
Stub is available in multiple regions. The same local-first approach applies everywhere. Limited purchase and entitlement data may be processed by Apple and RevenueCat in countries where they or their service providers operate, in line with their policies and applicable safeguards.
We may update this policy from time to time. Material changes will be reflected by updating the "Last updated" date above and, where appropriate, within the app.
