Privacy Policy

1. Who we are

Reetle (“we”, “us”, “our”) provides the Reetle iOS app, a companion application for Reetle Bluetooth Low Energy (BLE) e-ink hardware. The app lets you sign in, pair a device, transfer ebooks, images, notes, and audio, record voice notes, transcribe recordings, generate AI summaries and related content, manage to-dos, and purchase optional memberships.

The data controller for the app is the Reetle Team. Privacy requests should be sent to support@ereetle.com. We respond within 30 days.

2. Scope

This policy applies to personal data processed when you download, install, register for, or use the Reetle iOS app, including optional cloud features and in-app subscriptions.

It does not replace Apple’s privacy practices for Sign in with Apple, Apple In-App Purchase, Apple Reminders, on-device Speech Recognition, or the App Store. Those services are governed by Apple.

By creating an account or using the app, you acknowledge this policy. Where a feature requires consent (for example, microphone access or cloud upload of a recording), we request that consent in the app before the feature runs.

3. Information we collect

We collect only what is needed to operate the app. We do not collect data for advertising or cross-app tracking. Categories:

3.1 Account information

When you sign in with email, Google, or Apple, we collect:

• Email address
• Display name / nickname
• Profile photo, if you choose to provide one
• Internal account identifier
• Authentication tokens stored in the iOS Keychain

Google Sign-In requests only the email and profile scopes. Sign in with Apple may provide a relay email if you hide your real address. We do not receive your Google or Apple password.

3.2 Device and technical information

• Device model, iOS version, app version, and build number
• Network connectivity state (online / offline) to support offline-first caching
• Bluetooth connection state for the paired Reetle device
• Wi-Fi SSID / local-network identifiers only when needed to discover or transfer to nearby hardware
• Diagnostic and crash-style logs generated by the app, including logs attached when you submit feedback

We do not collect Advertising Identifier (IDFA). We do not use the App Tracking Transparency prompt because we do not track users across other companies’ apps or websites.

3.3 Content you create or import

Depending on the features you use, this may include:

• Ebooks and documents (PDF, EPUB, text, Word, MOBI, and similar formats you open or send to the device)
• Images you take or pick from the photo library to send to the device or set as an avatar
• Voice recordings, transcripts, timestamps, titles, and related metadata
• To-do items, notes, and AI-generated summaries, mind maps, or extracted tasks
• Feedback you send to support, including optional contact details

In Local Only privacy mode, new recordings and files stay on the device and are not uploaded. See Section 5.

3.4 Paired hardware information

When you connect a Reetle e-ink device we process device model, firmware version, battery / storage status where exposed by the protocol, connection logs, and file-transfer records. This is used to complete transfers, apply firmware updates you initiate, and diagnose connection issues. We do not scan or connect to unrelated Bluetooth devices.

3.5 Subscription and purchase information

If you subscribe through Apple In-App Purchase, we receive from Apple the product identifier, subscription status, period, and original transaction identifier needed to unlock membership. We do not collect, store, or see your credit card number, Apple ID password, or full payment credentials. Apple processes payment.

3.6 Information we do not collect

• Precise or coarse GPS location history — location permission is used only as an iOS prerequisite for BLE scanning and Wi-Fi identification; Reetle does not record your location
• Contacts, calendar, Health, HomeKit, or motion data
• Advertising IDs or third-party advertising profiles
• Payment card numbers
• The contents of photos or files you did not explicitly select

4. How we use information

We use personal data to:

• Create and authenticate your account, keep you signed in, and protect the account
• Discover, pair, and communicate with your Reetle hardware over BLE and, for larger files, local Wi-Fi
• Transfer, cache, display, and manage files you choose to send to or receive from the device
• Record, play, transcribe, summarize, and organize voice notes according to the privacy mode you selected
• Sync to-dos you enable with Apple Reminders
• Fulfill membership entitlements and credit / points consumption for optional cloud AI features
• Respond to support requests and investigate defects you report
• Maintain security, prevent abuse, and comply with law
• Operate offline-first caching so the app remains usable without a network

We do not use your recordings, documents, or photos to train advertising models, and we do not sell them. Cloud AI providers receive content only when you use a cloud feature and only as needed to complete that request.

5. Privacy modes

You choose how new recordings and files are stored. You can change this later under Profile → Data Privacy.

Switching to Local Only does not automatically erase content already uploaded. You can delete individual items in the app, or delete your account (see Section 13) to request deletion of cloud account data.

6. iOS permissions

Permissions are requested only when a feature needs them. Denying a permission disables that feature; the rest of the app continues to work. The usage strings in the app match the table below.

Background modes used by the app are audio (continue playback) and bluetooth-central (maintain the hardware connection). These modes are not used to collect data in the background for advertising.

7. Audio, speech, and AI processing

7.1 On-device transcription

In Local Only mode, transcription runs on the iPhone using Apple Speech Recognition and/or WhisperKit (Core ML). Audio and transcripts remain on device unless you later choose to upload them.

7.2 Cloud transcription and AI

If you use Cloud First mode or explicitly upload an item, audio or text may be sent to our API (api.ereetle.com) and to the cloud processors needed to complete the feature you requested, including:

• Cloud speech-to-text (including ElevenLabs transcription where that option is used)
• AI text summary, mind map, and to-do extraction
• Optional AI image generation and ebook-arrangement features that consume membership credits

Those providers process the input only to return the result. We do not authorize them to use your content for advertising. AI output can contain errors; it is not professional advice.

8. Third-party services

The app uses the following processors. Each processes only what is required for the listed purpose and is subject to its own privacy policy.

The iOS app does not include Firebase Analytics, Google Analytics, Crashlytics, advertising SDKs, or social-login SDKs other than Google Sign-In and Sign in with Apple.

9. Sharing, selling, and tracking

We share data only:

• With the processors listed in Section 8, under contract / platform terms, to operate the feature you used
• With Apple, as required for Sign in with Apple, In-App Purchase, and App Store operations
• If required by law, legal process, or to protect users, the service, or the public from harm
• In a business transfer (merger, acquisition), subject to this policy or equivalent protection

The app’s privacy manifest declares NSPrivacyTracking as false and lists no tracking domains.

10. Storage, security, and retention

10.1 Where data is stored

• On device: caches, Hive / local databases, Whisper models, and Keychain tokens. Offline-first: the app prefers local data and does not require a network for core browsing of cached content.
• In the cloud: account records on Reetle servers; uploaded files on Google Firebase Storage. Infrastructure may be located outside your country, including the United States.

10.2 Security

We use TLS for network traffic, Keychain for tokens, access control, least-privilege practices, and deletion of files you remove. No internet service is perfectly secure; please keep your device passcode enabled and do not share your account.

10.3 Retention

• Account data: kept while the account is active, then deleted or anonymized within 30 days after account deletion unless a longer legal period applies.
• Uploaded content: kept until you delete the item or the account; primary copies and routine backups are purged within 30 days after deletion.
• Local Only content: remains on the iPhone until you delete it or uninstall the app. Uninstalling removes on-device data we stored in the app container.
• Subscription records: retained as required for tax, audit, and dispute handling (typically several years for transaction identifiers received from Apple, not payment cards).
• Support / diagnostic logs: typically up to 90 days, longer if needed for a security incident you reported.

11. Children

Reetle is a productivity companion for e-ink hardware. It is not directed to children under 13 (U.S. COPPA) or under 14 (where that higher age applies). We do not knowingly collect personal data from children under those ages.

If you believe a child provided data without verifiable parental consent, email support@ereetle.com. We will delete or anonymize the data promptly.

12. Your rights

Subject to the laws that apply to you (including GDPR, UK GDPR, CCPA/CPRA, and China’s PIPL where applicable), you may:

• Access a copy of personal data we hold about you
• Correct inaccurate data (nickname and avatar can be edited in the app)
• Delete your account and associated cloud data (Section 13)
• Export data we hold, where technically feasible, in a commonly used format
• Withdraw consent for optional permissions in iOS Settings (Bluetooth, Microphone, Photos, etc.)
• Object to or restrict certain processing
• Lodge a complaint with your data-protection authority

California residents: we do not sell or share personal information as those terms are used in the CCPA/CPRA. We do not use or disclose sensitive personal information for purposes other than providing the service.

EEA/UK residents: depending on the feature, our legal bases include performance of a contract (account, transfers, subscriptions you purchase), consent (optional permissions and cloud upload), and legitimate interests (security, support, preventing abuse) that do not override your rights.

To exercise rights that the app does not already provide in Settings, email support@ereetle.com. We will respond within 30 days.

13. Account deletion (App Store Guideline 5.1.1(v))

How to delete

1. Open Reetle and sign in.
2. Go to Me (Profile).
3. Open Delete Account.
4. Read the warnings, confirm twice, and complete deletion.

What deletion does

• Permanently deletes account and profile information on our servers
• Permanently deletes cloud recordings, ebooks, and files associated with the account
• Clears local auth tokens and app caches on this device

What deletion does not do

• It does not cancel an Apple subscription. You must cancel auto-renewal in iOS Settings → [Your Name] → Subscriptions (or apps.apple.com/account/subscriptions) or you may continue to be billed by Apple.
• Content already copied onto your physical e-ink device remains on that device until you delete it there.
• Apple, Google, or a cloud AI provider may retain records they are legally required to keep, or that you stored in their systems independently of Reetle.

If the in-app flow fails, email support@ereetle.com from the address on the account and we will complete deletion.

14. Subscriptions and payments

Optional memberships (Lite, Pro, Plus; monthly or yearly) are sold as auto-renewing subscriptions through Apple In-App Purchase. Apple is the merchant of record.

• Payment is charged to your Apple ID.
• Renewal occurs unless you turn off auto-renew at least 24 hours before the period ends.
• Manage or cancel in iOS Settings → Subscriptions.
• Refund requests are handled by Apple at reportaproblem.apple.com.

15. Policy updates

We may update this policy when the product, law, or our processors change. The “Last updated” date at the top will change. Material changes will be communicated in the app or by email where appropriate. Continued use after the new effective date means you accept the updated policy. If you do not agree, stop using the app and delete your account.
