NightTalk is designed to keep sensitive night information on your device. It has no user account, no publisher-operated backend, no advertising, no analytics, and no third-party tracking SDK.
Who this policy covers
NightTalk is published by minh.systems. This policy covers the NightTalk iPhone and iPad app and this public support website. For privacy questions, contact the NightTalk publisher at mip@gmx.biz.
Information NightTalk processes
When you use NightTalk, the app may process the following on your device:
- night-session dates, duration, settings, and summaries;
- a bounded number of short audio clips associated with candidate voice events, which NightTalk subsequently filters locally;
- optional on-device transcripts and locally derived topics, keywords, and sentiment;
- favorite markers, custom moment titles, and private notes that you choose to add;
- optional summaries calculated from HealthKit sleep-analysis samples that you choose to share; and
- settings such as transcription language, HealthKit preference, retention period, and free-night usage.
How the app uses this information
NightTalk uses this information only to provide the features you choose on that device: recording a night you explicitly start, reviewing candidate events, presenting local insights, and optionally adding the HealthKit context you authorize. Pro tools let you organize saved moments, search locally, compare completed nights, and view a weekly recap calculated from recorded nights. Search terms are processed on the device, not sent to a search service. Comparisons and recaps are for personal reflection, not medical assessments. NightTalk does not use this information for advertising, marketing, profiling, sale, or tracking.
Other people in the room
A night recording can capture the voices of anyone nearby. Before each night, NightTalk asks you to confirm that nobody else is in the room or that everyone present knows about the recording and has agreed. Only record people who have given permission; recording laws vary by location. NightTalk is not intended to monitor other people, and it does not identify who is speaking.
Storage, sharing, and transfers
NightTalk stores its content in the app’s protected local container and excludes that content from iCloud Backup. The NightTalk publisher does not receive recordings, transcripts, favorite markers, titles, notes, search terms, HealthKit samples, insights, or usage telemetry. The app does not include a publisher-operated cloud service or third-party analytics/advertising SDK.
Optional transcription uses Apple’s on-device Speech framework where available. Optional HealthKit import uses Apple’s HealthKit framework. Purchases are processed by Apple through StoreKit. Apple may process information under its own privacy terms to provide its services; the NightTalk publisher does not receive payment-card information.
Health information
HealthKit access is optional and read-only. If you enable it and grant access, NightTalk reads sleep-analysis samples overlapping a recorded session to calculate local sleep-duration, efficiency, stage, and timeline summaries. It does not write HealthKit data, access Clinical Health Records, use HealthKit data for advertising or marketing, or conduct health research.
Your choices and deletion
You can turn optional transcription and HealthKit import on or off, change permissions in iOS or iPadOS Settings, choose a retention period from 7 to 90 days, and use Settings → Delete All NightTalk Data to permanently remove NightTalk sessions, audio clips, transcripts, favorite markers, custom titles, private notes, and HealthKit-derived summaries stored by the app. Favorite moments and their notes are not exempt from retention: they are deleted when their source night expires or is deleted. Comparisons and recaps are calculated from the remaining nights. Deleted nights cannot be restored. Preferences and the local free-night counter remain because they are app settings and product-access state rather than user-created night content.
Because NightTalk has no account or publisher-held copy of your app data, the publisher cannot remotely retrieve, correct, export, or delete it. Use the in-app controls to manage it directly.
Retention and permission changes
App retention cleanup runs at launch and after completed sessions. Shortening the retention period asks for confirmation and removes older completed nights. A closed or uninstalled app does not run background cleanup. Stop active recording and finish processing before using Delete All NightTalk Data. Removing the app deletes local content; no NightTalk cloud recovery is available.
You can revoke microphone and Speech access in system Settings and HealthKit read access in Apple Health’s app-access controls. Disabling an optional feature prevents future processing but does not erase previously saved transcripts or imported summaries. Delete that content with the in-app data controls. Deleting NightTalk’s HealthKit-derived summaries does not delete the original Apple Health records.
Website and support email
This website is hosted on GitHub Pages. The site itself does not use a contact form, advertising, analytics scripts, tracking cookies, external fonts, or embedded media. GitHub may process technical request information such as IP addresses, browser information, and access times to operate and secure hosting, under the GitHub Privacy Statement. This is separate from the app’s local night data. If you choose to email mip@gmx.biz, the support inbox processes the email address, message, and attachments you provide solely to respond to your request and maintain necessary support records. Support is available only by email. Messages travel through your email service and the GMX mailbox provider; the website does not upload or collect them. Do not send recordings, transcripts, Health data, passwords, or payment details. Support messages are retained only while needed to handle the request, necessary follow-up, or applicable record-keeping obligations. You may request deletion of support correspondence by writing to the same address; any legally necessary retention will be explained.
Children and medical use
NightTalk is not directed to children and is not offered in the App Store Kids category. It is a personal wellness and reflection tool, not a medical device. It does not diagnose, monitor, prevent, or treat any condition, and its possible voice-event detections may be incomplete or inaccurate.
Changes and contact
If this policy changes materially, the effective date will be updated here and relevant in-app and App Store disclosures will be updated as required. Questions can be sent to mip@gmx.biz.
