HashA home for your records
Privacy Policy
From a quick note to events and tasks.
Here is how Hash uses your information and where it stores it.
Hash (the “app”) is a personal record app that organizes notes, events and tasks using hashes (tags). This policy applies to Hash on iPhone, iPad and Mac, the connection and AI features of Hash for Windows, and this privacy policy website. The operator is Yoonspace (the operator of Hash).
Records are stored on your device by default. No separate Hash account is required.
iCloud, sharing, AI and link previews may send the information they need outside your device.
You can adjust sync, AI and permissions, and export or delete your records.
The operator does not collect your records for advertising or sale. The current app does not include advertising SDKs, analytics SDKs for tracking users, or a feature that collects records on the operator’s server.
The app uses note text, hash names, colors and icons, events, deadlines, recurrence and completion history, reminder times and places, links, selected photos and attachments, themes and images, and creation and modification times to store, display, search, remind and sync. Some usage state, such as search queries and recently opened records and hashes, is kept on your device for search and rediscovery features.
The app reads files you select on your device, including KakaoTalk self-chat exports, data files and photos from the previous Hash app, and AI kit responses, and converts them into records. It does not sign in to your Kakao account or retrieve conversations from Kakao’s servers. After import, records are processed according to your sync, sharing and AI settings.
To create a link’s title, description, thumbnail and reading text, the app connects directly to the website and image URLs. These destinations may receive ordinary communication information such as the requested URL, IP address and browser identification information. Extracted content is saved with the link record and may be included in sync or AI input.
Hub connections use device names and identifiers, PC addresses, connection keys, model names and processing performance, and job status. If you email a privacy inquiry, we process your sender email address, message and any attachments you send to respond and handle your request. You do not need to include sensitive records that are unnecessary for resolving the issue.
The permissions below are requested when you use an available feature. The current App Store release does not provide Hub or PC connections and does not use camera or local network permissions. If you decline, you can still use record creation and search features that do not require that permission.
Record titles or content may appear in widgets, the Today card on the lock screen, notifications and Spotlight search. If you share a device, check what these features display.
Processing depends on device support and app settings. AI input may include the text of the record being processed, content extracted from links, a list of hashes and task instructions. Results may be saved as summaries, hash suggestions, tasks or drafts.
On supported devices, the app uses Apple Intelligence’s on-device model for hash suggestions and summaries. Hash suggestions that run automatically when you save a record always use the on-device model only. Input processed by the on-device model does not leave the device.
On supported devices running iOS, iPadOS or macOS 27 or later, when you request a summary, the app may process it with Apple’s Private Cloud Compute (PCC) if the text is long, combines many sections or items, or the on-device model could not process it. In that case the record text, the reader text extracted from its link and the task instructions are sent to Apple. Apple states that PCC uses requests only to produce the response, does not store them, and lets independent researchers verify these claims. The operator does not receive what is sent to PCC or its results.
PCC has a daily usage limit per iCloud account and is subject to the Apple Intelligence Terms and Conditions. Turning off “Switch to Apple cloud automatically” (on by default) in Settings → AI stops PCC use, and records in hashes with “Exclude from external AI and Apple cloud” turned on are never sent to PCC. Where a request was processed is shown in Settings → AI and in the summary confirmation.
The current iPhone, iPad and Mac App Store release does not provide Hub or PC connections or automatic Hub analysis. The following describes Windows Hash and development builds with Hub enabled. A Mac connected through the same iCloud account or a directly paired Windows PC can analyze records using a local model. When “Automatically analyze long notes and tasks” is enabled, eligible records are processed automatically. In versions that provide Hub, this setting is enabled by default. Mac connections use iCloud sync; direct Windows connections use encrypted communication with the paired PC. Records, jobs and results sent to the PC are also stored there. You can turn off automatic analysis or disconnect the PC. Information already stored on the PC must also be managed on that PC.
“Send to AI” and record and theme kits turn selected content into prompts or files you can copy or share. If you paste or share it with an external AI service, that service processes the information. Check the content you will send and whether it includes sensitive information. Retention, use for training and deletion after transfer depend on the policies and settings of the service you choose.
AI results are suggestions. The app displays summaries and recommendations separately, and saves drafts or plans as new records after you review them. The operator does not collect your records to train a separate AI model.
Electronic information is removed through the app’s deletion features or the relevant storage service’s deletion procedures. The operator cannot delete external copies you create yourself; please also remove them from their respective storage locations.
In your operating system’s settings for Hash, you can change location, photo, calendar, camera, notification and local network access. Notification previews, widgets and lock screen cards can also be managed through system and app settings.
App settings let you control iCloud sync and on-device hash suggestions. You can also manage external AI exclusions for individual hashes and shared space permissions. In Settings → AI you can turn automatic switching to Apple cloud on or off and check your daily Apple cloud usage. The current App Store release does not provide Hub and PC connections. Development builds with Hub enabled and Windows Hash provide separate controls for automatic analysis and PC connections.
Open a record in the app to edit or delete it. Use Settings → Export & Backup (내보내기·백업) to export Markdown files, and Settings → Recently Deleted (최근 삭제됨) to manage deleted records.
Send requests to access, correct or delete personal information, stop processing, or withdraw consent to the email below. You may also submit a request through an authorized representative or legal guardian. If necessary, we verify your identity or the representative’s authority using only the information needed, handle the request according to applicable law and tell you the result. For device or personal iCloud records the operator cannot access, we explain how you can manage them yourself.
Withdrawing permission may limit the relevant feature. If the law limits a request, we explain why. You may also contact South Korea’s Personal Information Infringement Report Center for privacy advice or reports, or the Personal Information Dispute Mediation Committee for dispute mediation.
The app uses the operating system’s app storage and access permissions. The app, widgets and share extension exchange the information they need within the same app group; ordinary records are not uploaded to a public database. Content synced through iCloud uses CloudKit’s encrypted fields, and large bodies of text and attachments are separately encrypted. Access to shared data follows CloudKit participation permissions.
Records and results sent over a direct Windows Hub connection are encrypted using the connection key. On iPhone, that key is stored in the device’s Keychain. This website is served over HTTPS. The operator restricts access to inquiry information and operational accounts to what is necessary.
This policy page does not use its own cookies, advertising trackers, analytics scripts or browser storage. Hosting and security services may separately process ordinary connection information. The app’s AI assists with organizing records and writing; it is not used to make automated decisions that significantly affect your rights or obligations.
The privacy contact is Yoonspace (the operator of Hash).
