Privacy Policy

Last updated: July 25, 2026

Bitbook is a stand-up comedy notebook. Your jokes are your intellectual property, and Bitbook treats them that way.

Who Is Responsible

Bitbook is made by Sammy Gutiérrez, an individual developer, who is the data controller for the limited purposes described here. You can reach me at support@bitbook.lol.

The Short Version

• All your data stays on your devices and in your personal iCloud account.
• Nothing is sent to a third-party server; the only sync is to your own iCloud.
• No accounts, no third-party analytics, no tracking, no ads.
• All audio, text, and AI processing happens on your device.

Data You Create

Bitbook stores the content you create (bits, set lists, labels, performances, recordings, venues, and notes) in a local database on your device. If you have iCloud enabled, this data syncs across your devices through your personal iCloud account using Apple’s CloudKit. Bitbook never has access to your iCloud data.

Audio & Video Recordings

Performance recordings, voice memos, and practice recordings are stored on your device. If iCloud sync is on, they also sync through your personal iCloud, and your other devices download them on demand. They are never sent anywhere else.

Transcription

Audio transcription uses Apple’s on-device Speech framework. Your audio is processed entirely on your device and is never sent to a server for transcription. Transcripts are part of your library: they stay on your device, sync through your personal iCloud if sync is on, and are never shared with anyone else.

Laugh Analysis

Laugh detection uses Apple’s on-device Sound Analysis framework. Like transcription, all processing happens on your device. Laugh analyses are part of your library: they stay on your device, sync through your personal iCloud if sync is on, and are never shared with anyone else.

On-Device Intelligence

Some features use Apple’s on-device language and image models: suggesting a title for a bit from its transcript, describing images you attach, and answering questions about your own material. All of it runs on your device. Your bits, recordings, and transcripts are never sent to a server for these features, and they are never used to train any model.

To make that possible, the app downloads a model from Apple’s servers the first time a feature needs one, using Apple’s Background Assets system. It downloads on demand rather than at install, and the transfer is one-way: nothing about you or your material is sent as part of it.

Location Data

Bitbook can capture your current location (with your permission) when you log a performance, so the venue is saved alongside it. Location is only read while you are actively using the app, never in the background, and the captured coordinates are stored with the performance on your device (and synced through your personal iCloud if enabled).

Apple Services

Bitbook integrates with the following Apple services at your discretion. Each requires your explicit permission:

• iCloud. Syncs your library across your devices: bits, set lists, labels, performances, venues, recordings, transcripts, and analyses.
• Microphone. Required to record voice memos and performance or practice audio. Recordings stay on your device.
• Camera. Required to record performance or practice video. Captured video stays on your device.
• Photo Library. Used when you add an image to a bit or to a performance.
• Speech Recognition. Used on-device for transcribing voice memos and recordings.
• Calendar. If you enable calendar sync, performance dates and venue details are written to your Apple Calendar.
• Notifications. Local, on-device reminders for upcoming performances. No external push notification service is used.
• Siri & Shortcuts. You can create bits and log performances via Siri. These interactions stay on your device.
• Spotlight. Bitbook indexes your content for on-device search. This data does not leave your device.

Data Collected

Bitbook has no analytics service, no advertising network, and no third-party SDK that collects data. The app does not transmit your content anywhere, and there is no Bitbook server for it to go to. Two narrow exceptions are worth naming plainly.

Apple Diagnostics

Bitbook records its own performance measurements using Apple’s MetricKit, which the system folds into the diagnostic data it already manages. If you have turned on Share With App Developers (Settings › Privacy & Security › Analytics & Improvements), Apple shares aggregated crash and performance reports with me. That sharing is handled entirely by Apple, it is off unless you turn it on, and it describes how the app behaved, not what you wrote. You can turn it off at any time in the same place.

Diagnostic Reports

Bitbook can generate a diagnostic report containing app and device information, the app’s own logs, and database statistics such as how many bits and performances you have. The report is written to your device, and it goes nowhere unless you choose to send it, for example when you report a bug. You can read it before you do.

Data Sharing

Bitbook does not share your data with any third party. The only data that leaves your device is:

1. iCloud sync to your own Apple account, encrypted by Apple.
2. Individual bits that you explicitly share via the Share Extension or Messages.
3. Material you explicitly share for notes with people you invite. Only the people you invite can see it, it moves through iCloud, and transcripts and laugh analyses are never included.

Everything else stays on your device.

Data Storage & Security

• All data is stored in your app’s sandboxed container or your personal iCloud account.
• iCloud data is encrypted in transit and at rest by Apple.
• Transcripts and laugh analyses follow the same rule as everything else: your device and your personal iCloud, nowhere else.

Retention and Location of Data

I don't hold your material, so there's nothing for me to retain or delete on your behalf. Your content stays on your device for as long as you keep it, and in your iCloud account for as long as you keep it there. Where iCloud stores and processes that data, including any transfer between countries, is determined by Apple under your iCloud account.

Data Deletion

• You can delete any bit, set list, label, performance, venue, or recording at any time from within the app.
• Deleted items are moved to Recently Deleted, then permanently removed.
• You can bulk-delete all transcriptions and laugh analysis data from Settings.
• Uninstalling Bitbook removes all local data. iCloud data can be removed from your iCloud settings.

Your Rights

Depending on where you live, you may have rights over your personal information under laws such as the GDPR in the European Union, the UK GDPR, or the CCPA in California. Those rights include access, correction, deletion, portability, and objection.

In Bitbook’s case there is very little for those rights to reach, because the app holds your material on your own device and in your own iCloud account, and I hold none of it. Your material is yours to export or delete at any time from inside the app, as described above. Your personal information is never sold or shared, and it is not used for advertising or profiling.

If you believe I hold personal information about you and you want to exercise a right over it, email support@bitbook.lol. If you are in the European Union or the United Kingdom, you also have the right to complain to your local data protection authority.

Children’s Privacy

Bitbook does not knowingly collect information from children under 13. The app contains no age-restricted content.

Changes to This Policy

If this policy changes, the updated version will be posted here with a new “Last updated” date. Since Bitbook doesn’t collect your email or any contact information, there’s no way to notify you directly, so check back here from time to time.
