On This Day -- Privacy Policy

Effective: September 1, 2025

Summary

On This Day is designed to work entirely on your device. We do not collect, store, or sell personal data. We use privacy‑first, anonymized analytics (TelemetryDeck) to understand basic app usage and improve the product. We do not use advertising SDKs and we do not track you across apps or websites.

Data We Access (with your permission)

  • Photos: Read your photo library to show photos taken on this calendar day across past years. If you choose to save favorites or delete photos, those actions occur in your local Photos library.

  • Notifications (optional): If enabled, we schedule a daily local reminder on your device. No notification data leaves your device.

What We Store

  • On device: Lightweight app metadata (e.g., save decisions, queued deletions, streak statistics) is stored locally using Apple frameworks.

  • iCloud (optional, private): If iCloud syncing is enabled by the system for app data, certain small metadata (not your photos) may sync through your private iCloud container via Apple's CloudKit. This data is tied to your Apple ID and is not accessible to the developer.

Telemetry (Analytics)

  • Anonymized usage: We use TelemetryDeck, a privacy‑first analytics SDK, to collect basic, anonymous signals about how On This Day is used (for example, that the app launched or that the settings screen was viewed). These signals help us fix issues and prioritize features.

  • No personal data: Signals do not include your name, email, phone number, photo content, or any identifying information. TelemetryDeck anonymizes identifiers on‑device before transmission.

  • No sales or ads: Usage information is not sold, shared for advertising, or used to profile you.

What We Do Not Do

  • No collection of personal data by the developer

  • No advertising SDKs

  • No tracking across apps or websites

  • No upload of your photos or their contents to developer‑controlled servers

Your Choices & Controls

  • You can revoke Photos or Notification permissions in iOS Settings at any time.

  • You can clear locally stored app data from the in‑app Settings (Reset / Clear Pending Deletes).

  • Deleting the app removes all on‑device app data.

Data Sharing

We do not share your data with third parties.

Children's Privacy

The app is rated 4+ and does not collect personal data.

Plain English

Far too many times we've seen apps harvest your contact database for spam, for profit, or for just doing gross stuff. On This Day collects basic information about how you interact with the app, but that information is used solely to help make On This Day better. Furthermore, this information cannot be tied back to you; it is completely anonymized. This usage information is not and will not be for sale.

Legal Mumbo Jumb

Personally‑Identifying Information

On This Day does not gather or transmit any Personally‑Identifying Information outside of your local device. It only stores preferences and lightweight app metadata within its own databases. Your photos are stored within your device's photo library. Anonymous usage telemetry is collected to improve the app and cannot be linked back to you.

Business Transfers

If On This Day, or substantially all of its assets, were acquired, or in the unlikely event that On This Day goes out of business or enters bankruptcy, this policy and its effects may change or be amended. Since On This Day does not collect information about you--other than anonymized usage data--nor your photos, it's unlikely this privacy policy will materially change.

Privacy Policy Changes

Although most changes are likely to be minor, On This Day may change its Privacy Policy from time to time, in its sole discretion. Your continued use of this app after any change in this Privacy Policy will constitute your acceptance of such change.

Indemnity

You hereby indemnify us and undertake to keep us indemnified against any losses, damages, costs, liabilities and expenses (including, without limitation, legal expenses and any amounts paid by us to a third party in settlement of a claim or dispute on the advice of our legal advisers) incurred or suffered by us arising out of any breach by you of any provision of these terms of use, or arising out of any claim that you have breached any provision of these terms of use.
