Privacy Policy

Last updated: June 3, 2026

The short version

dim collects almost nothing. We store your email so we can manage your subscription, and that is the only personal thing that reaches our servers.

Your child's name, age, pronouns, and favorites never leave your device. The stories are personalized right there on your phone, never on our end.

We use two anonymous tools to see which stories get opened and to fix crashes. None of it is tied to you or your child, and none of it is ever used for advertising. We do not sell your data, and we do not track you across other apps or websites.

The longer notice below covers the legal detail, region by region. If you ever have a question, email hello@fourfiftyone.co.

1. What information do we collect?

Personal information you disclose to us

We collect personal information that you voluntarily provide to us when you subscribe to dim, contact us, or otherwise interact with the Services. The personal information we collect is:

  • email addresses

What stays on your device. dim stores all child profile information, such as your child's name, age, pronouns, and favorites, only on your device and in your own iCloud. This information is never sent to our servers. Story personalization happens entirely on your device, at the moment you read.

Sensitive information. We do not process sensitive information.

Payment data. dim does not collect or store any payment card details. All payments are processed by Apple through the App Store, and subscription status is managed by RevenueCat. You may review their privacy notices at apple.com/legal/privacy and revenuecat.com/privacy.

Push notifications. We may request to send you push notifications regarding certain features of the app. If you wish to opt out, you can turn them off in your device's settings.

Information automatically collected

Some information, such as a per-install identifier and information about how the app is used, is collected automatically when you use the Services. This information does not reveal your specific identity but supports the security, operation, and improvement of dim. It includes:

  • Log and usage data. Diagnostic and usage information such as crash reports, performance data, and which features and stories are used. This is collected through Sentry (crash and performance diagnostics) and TelemetryDeck (anonymous usage analytics).
  • Device data. A random, per-install identifier used by TelemetryDeck and Sentry. These identifiers are not the advertising identifier, are not tied to you or your child, and are regenerated if the app is reinstalled.

We do not collect your precise or coarse location.

2. How do we process your information?

We process your personal information for the following purposes:

  • To deliver and manage the Services. We use your email and subscription status to give you access to dim and manage your subscription.
  • To respond to you and provide support. We use your email to answer your requests.
  • To identify usage trends. We process anonymous usage information to understand how dim is used so we can improve it.
  • To keep the Services safe. We process anonymous diagnostic information to fix crashes, monitor performance, and protect against abuse.
  • To send you communications. Where permitted, we may send you service messages, and marketing or promotional messages you can opt out of at any time.
  • To comply with law. We process information where necessary to meet legal and tax obligations.

We do not profile you or make automated decisions that produce legal or similarly significant effects.

3. What legal bases do we rely on?

If you are located in the EU or UK, this section applies to you. The GDPR and UK GDPR require us to explain the valid legal bases we rely on to process your personal information. We may rely on the following:

  • Performance of a contract. To deliver dim, manage your subscription, and provide support using your email.
  • Legitimate interests. To maintain, secure, and improve the app using anonymous analytics and crash reporting, where those interests do not outweigh your rights. For example, to analyze how the Services are used so we can improve them, and to diagnose problems and prevent abuse.
  • Legal obligations. To keep transaction and tax records and to comply with applicable law.

If you are located in Canada, this section applies to you. We may process your information if you have given us express or implied consent, and you may withdraw that consent at any time. In some exceptional cases permitted by law, we may process information without consent, for example to detect and prevent fraud, or where required by a subpoena, warrant, or court order.

4. When and with whom do we share your personal information?

We share personal information only with the service providers that help us operate dim, under written agreement, and only what each one needs:

  • Apple. Processes payments and provides iCloud, which holds your own on-device data under your control.
  • RevenueCat. Manages your subscription status.
  • TelemetryDeck. Provides anonymous usage analytics using a random, per-install identifier not tied to you or your child. Privacy notice: telemetrydeck.com/privacy.
  • Sentry. Provides crash and performance diagnostics using a random, per-install identifier and no personal information. Privacy notice: sentry.io/privacy.
  • Sanity. Stores the story content you read in the app.
  • Cloudflare. Hosts the small service that handles your subscription and account email.

We may also share or transfer your information in connection with a merger, sale of assets, financing, or acquisition of all or part of our business. No child data is ever shared with any third party. We do not show advertising and do not share data with advertisers.

5. How long do we keep your information?

We keep your personal information only as long as necessary for the purposes in this notice, unless a longer period is required or permitted by law (such as tax or accounting requirements). We keep your email for as long as you use dim. We keep transaction and subscription records longer where required for tax and accounting purposes. Anonymous usage and diagnostic data is retained in anonymized form for analytics and reliability.

When we no longer have a legitimate need to process your information, we will delete or anonymize it, or securely isolate it where deletion is not immediately possible.

6. How do we keep your information safe?

We have implemented appropriate technical and organizational security measures to protect your personal information, including encrypted connections, and we limit what we collect to reduce risk. However, no method of transmission or storage can be guaranteed completely secure, so we cannot promise or guarantee absolute security.

7. Do we collect information from minors?

dim is a bedtime story app intended to be used by a parent or guardian, who reads the stories aloud to their child. dim is designed for children ages 2 to 8, but it is the parent or guardian who sets up and operates the app.

We do not knowingly collect any personal information directly from children. Any child profile details a parent chooses to add, such as a child's name, age, pronouns, or favorites, are stored only on the device and in the parent's own iCloud. This information is never transmitted to our servers and is never shared with any third party. It is used solely on the device to personalize the stories at the moment they are read.

The only personal information we collect on our servers is the parent's email address, used to manage the subscription. If you believe we have inadvertently collected personal information from a child, please contact us at hello@fourfiftyone.co and we will delete it promptly.

8. What are your privacy rights?

Withdrawing your consent. Where we rely on your consent, you may withdraw it at any time by contacting us. This will not affect the lawfulness of processing before withdrawal.

Opting out of marketing. You can unsubscribe from marketing messages at any time using the unsubscribe link in our emails, or by contacting us. We may still send you service messages necessary to administer your subscription.

Depending on your location, you may have rights under applicable data protection laws. These may include the right to access, correct, delete, or obtain a copy of your personal information, to restrict or object to its processing, and to data portability. For dim, the personal information we hold is your email and subscription status.

If you are in the EEA or UK and believe we are unlawfully processing your personal information, you may complain to your local data protection authority or the UK Information Commissioner's Office. If you are in Switzerland, you may contact the Federal Data Protection and Information Commissioner.

To exercise any right, email hello@fourfiftyone.co. We will respond in accordance with applicable law.

9. Controls for Do-Not-Track features

Most browsers and some mobile systems offer a Do-Not-Track ("DNT") setting. Because no uniform standard for recognizing DNT signals has been finalized, we do not currently respond to them. If a standard is adopted, we will update this notice.

10. Do United States residents have specific privacy rights?
