Last updated: 01/05/2026Who we are
Holdt is an iPhone app that helps you track your recurring subscriptions. It is developed by Diogo Martins, based in Portugal. If you have any questions about this policy, you can reach us at [email protected].The short version
Your subscription data never leaves your phone. We don't have a server. We don't track you. We don't sell data. The only time anything leaves your device is when you verify a purchase or voluntarily send us feedback.What data we collect and where it lives
Your subscription data — stored only on your device.
Everything you enter into Holdt (subscription names, amounts, billing dates, notes) is stored locally on your iPhone using AsyncStorage. We cannot see it, access it, or retrieve it. It never touches our servers because we don't have any.- Purchase verification — handled by RevenueCat
When you buy a premium plan, Apple generates a signed receipt. That receipt, along with an anonymous device identifier, is sent to RevenueCat, Inc. to verify your purchase. RevenueCat does not receive your name, email address, IP address, or any subscription data you've entered into the app. RevenueCat processes this information to confirm your entitlements. You can read RevenueCat's privacy policy at revenuecat.com.- Feedback and bug reports — optional.
If you use the in-app feedback form, your message — and your email address if you choose to include it — is sent to a private Discord channel via webhook. We use this only to respond to you and to improve the app. We do not share it with anyone. If you don't submit feedback, nothing is sent.- Local notifications — entirely on-device.
Reminder notifications for upcoming renewals are scheduled and delivered entirely on your iPhone. No data is transmitted anywhere for this feature.What we do not collect
We do not use analytics tools, advertising SDKs, tracking pixels, or third-party cookies. We do not collect your name, email, location, or device identifiers for our own purposes. We do not build profiles. We do not have a backend database storing your information.Your rights under GDPR
You are based in, or protected by the laws of, the European Union. That gives you the following rights:
Access. You have the right to know what personal data we hold about you. The only personal data we could hold is an email address you voluntarily gave us via the feedback form.
Correction. You can ask us to correct any inaccurate personal data we hold.
Deletion. You can ask us to delete any personal data we hold. For feedback emails, contact us and we will delete them from our Discord channel. For your subscription data inside the app — because it lives entirely on your device — deletion means uninstalling Holdt. When you delete the app, all that data is gone.
Portability. You can request a copy of any personal data we hold about you.
Objection. You can object to how we process your data.
To exercise any of these rights, email us at [email protected]. We will respond within 30 days.
If you believe we are handling your data unlawfully, you have the right to lodge a complaint with Portugal's data protection authority, the CNPD (cnpd.pt).Legal basis for processing (GDPR)
We process purchase verification data because it is necessary to perform the contract with you (delivering the premium features you paid for). We process feedback data based on your explicit consent when you choose to submit it.Data retention
Purchase verification data is held by RevenueCat according to their retention policies. Feedback emails are kept in our Discord channel until we delete them, typically within 12 months of receipt. Your in-app subscription data is kept on your device until you delete the app.Children
Holdt is not directed at children under 13. We do not knowingly collect data from children.Changes to this policy
If we make material changes, we will update the "Last updated" date at the top of this page. Continued use of the app after changes means you accept the updated policy.
