Privacy Policy

Effective September 24, 2026

Silk is a Screen Time app. It blocks apps you choose on your iPhone and lets you spend a daily budget of minutes to open them. This policy lists what Silk stores and what it does not collect. Nothing leaves your device.

What Silk stores, and where

Silk stores its data on your iPhone, in a shared container used by the app and its Screen Time extensions (an App Group). It stores:

• The apps and websites you chose to block, and the apps you named for spending.
• Your daily minute budget, any per-app ceiling, and your down-hours window.
• A record of the grants Silk has issued: how many minutes, for which app, and when.
• A log of the times a blocked app's or website's screen was shown, kept to the most recent 2,000. Silk uses it to score the day. It records a time and nothing else: not which app, and not what you did next.
• A summary for each past day, kept to the most recent 2,000: how many times a blocked app's screen was shown and how many of those fell in down hours, the minutes granted, and how many grants were spent. The day's score is worked out from these when Mirror shows it; it is not stored.
• The times Silk's own daily check-in ran, kept to the most recent 2,200, so Silk can tell whether its re-lock layers have been waking.
• The state of a request that is still in progress, and the date Silk was set up.

Silk has no server, so none of this is uploaded. If you use iCloud backup, this data is included in the backup the same way any other app's local data is, under Apple's backup encryption.

Screen Time: what Silk can and cannot see

Silk uses Apple's FamilyControls, ManagedSettings and DeviceActivity frameworks. You authorize Silk for yourself as an adult, using Apple's individual authorization. Silk is not a parental control product and does not manage another person's device or account.

You choose the apps to block in Apple's own picker. Silk receives an opaque token for each one. It does not learn the name, bundle identifier, or icon of any app you block that way, because Apple's API does not expose them. The apps you name for spending are different: you pick their names from Silk's own short list, and that name is what Silk stores with that app's settings and with each grant, so the bar can answer "Instagram is open for 10 min." Silk does not read your Screen Time usage data and never sees how long you spent in any app. To lock an app again, Silk asks iOS to signal when the app has been used for the minutes granted; iOS keeps the count, and Silk never sees it. The minute figures Silk shows are computed from the grants it issued, not from your device usage.

What Silk does not collect

Silk has no network code and no server. It has no accounts or sign-in, no analytics, no crash reporting, no advertising or ad identifiers, and no access to location, contacts, photos, or the microphone. It does not track you across apps or websites. It does not ask for notification permission. Silk's privacy manifest, in the format Apple requires of every app, declares that no data types are collected.

On-device language processing

On a device with Apple Intelligence available, Silk may use Apple's on-device FoundationModels framework to read a wider range of phrasing when you type or dictate a request. That processing runs on your device. Your request is not sent to Silk, to Apple, or to anyone else. (If you dictate, or use Siri or Shortcuts, Apple handles that input under Apple's own privacy policy.) On any other supported device, Silk reads the same requests with its own built-in parser.

No third parties

Silk includes no third-party SDKs and shares no data with anyone. There are no advertising partners, analytics vendors, or data brokers.

Children

Silk is not directed at children. It uses Apple's adult self-authorization and is meant for a person managing their own phone use, not for a parent managing a child's device.

Deleting your data

• Delete the Silk app. That removes its local storage, including every grant record and setting.
• To remove Silk's Screen Time access without deleting the app, go to Settings > Screen Time > Apps with Screen Time Access, and turn Silk off.

Changes to this policy

If this policy changes, the effective date above changes with it, and the new text is posted here before it takes effect. Silk has no way to contact you, so this page is the only notice.

Contact

Silk is published by Sanil Desai, an individual developer. Silk stores data only on your device and sends none of it anywhere, so there is nothing held about you to request, correct, or erase beyond what deleting the app removes. Questions about this policy go to the address below.
