Pinclip Data Handling

URL Sharing and Metadata Fetching

When you share a URL to Pinclip through the iOS share sheet, the app fetches Open Graph (OGP) / oEmbed metadata for that URL — such as the title and thumbnail image URL — and stores it on your device. These requests are sent directly to the origin website (YouTube, TikTok, etc.) or to the respective platform's public API; they do not pass through our servers.

You can edit or delete saved URLs, titles, thumbnails, notes, tags, and folder data at any time. You are responsible for the content you save. The app must not be used to store or share unlawful content, or content that infringes the copyright, privacy, or other rights of third parties.

iCloud Sync

For Pro subscribers, saved data (folders, clips, thumbnails, notes, tags) is stored and synced via your Apple iCloud account in a private CloudKit database. This data is transmitted and stored encrypted within Apple's infrastructure; we have no access to it and it is not transmitted to our servers.

On the free plan, data is stored only in local device storage and is not synced across devices. Sync may be delayed or fail depending on your iCloud sign-in status, available storage, and network conditions; the specifics are governed by Apple's iCloud terms.

Location Data (ThanYesterday)

The app uses your device's location to provide weather data. Location data is not stored on any server and is used only temporarily for weather API requests. Location access can be changed at any time in iOS Settings.

YouTube API Usage (Sidefeed)

"Powered by YouTube." Sidefeed uses the YouTube Data API v3 to display public video metadata (titles, thumbnails, channel names, publish dates, durations, etc.).

Sidefeed does not request Google account authentication or access to your personal YouTube data (liked videos, subscriptions, or watch history). Our server (Cloudflare Workers) centrally calls the YouTube API to fetch country- and category-level popular videos, temporarily caches them, and the app reads only from this server cache.

Sidefeed's use of the YouTube API is subject to the and the . By using the app, you agree to these terms and policies.

Server cache data is automatically refreshed and expired within at most 48 hours, and is not retained beyond the period permitted by YouTube's Developer Policies (30 days). Videos that are deleted or made private on YouTube are reflected in the next cache refresh cycle.

Voice Recording and Recognition (Talk Memo)

Talk Memo records audio via the Apple Watch microphone and uses on-device speech recognition (Apple Speech Recognition) on iPhone to convert recordings to text. All recordings and transcribed text are stored on-device only and are never transmitted to external servers. Accuracy of speech recognition is not guaranteed.

Users are responsible for the content of their recordings. Using the app to record conversations without the consent of all parties involved, or any other use that violates applicable laws, is prohibited.
