MindFox (“MindFox,” “we,” “us”) is a local-first thought-capture and organization app. It lets you record or type thoughts, save memories and tasks, optionally use AI to organize saved text, ask questions about your memories, generate reviews, create local reminders, and export or back up your information.
This Privacy Policy explains what information MindFox processes, how it is used, where it is stored, when information may be sent to third parties, and what controls are available to you.
You may type a thought directly into MindFox.
Typed content may be stored locally as:
Typing and saving a thought does not require Google AI.
If Google AI is disabled, the thought is saved locally without being sent to Google Gemini.
If you choose voice capture, MindFox requests microphone permission.
During voice capture, MindFox records audio and stores recording segments in the app’s private local storage.
Recordings have a 20-minute safety limit.
MindFox does not use an always-listening wake word.
A voice capture may also be started or finished through supported Apple system features such as Siri, Shortcuts, or an Action Button shortcut. The same MindFox microphone, transcription, storage, and privacy rules apply.
Audio retention depends on transcription status and your settings.
If transcription is complete and Keep audio after transcription is turned off, MindFox normally removes the completed local audio after the thought has been successfully saved.
If Keep audio after transcription is turned on, the recording may remain locally so you can replay or deliberately share it.
Incomplete or interrupted recordings may remain locally so MindFox can attempt transcription recovery.
When you delete an associated memory or use Delete all data on this device, MindFox attempts to remove the corresponding locally stored recording.
Raw voice recordings are not sent to Google Gemini.
MindFox uses Apple’s Speech framework to convert recorded speech into transcript text.
Microphone permission and Speech Recognition permission are requested separately.
MindFox provides an On-device speech only preference.
When supported by the selected language and device, speech recognition can be required to occur on-device.
If on-device-only recognition is selected and is not supported for that language or device, MindFox does not intentionally fall back to server-based recognition for that request.
If server-based Apple Speech Recognition is used, audio may be transmitted to Apple to perform speech recognition.
Apple’s processing and retention of speech-recognition information are governed by Apple’s applicable privacy policies and system settings.
Google Gemini is not used to transcribe the original audio.

A saved MindFox memory may contain information such as:
Saved memories are stored locally using Apple’s SwiftData framework and related private application storage.
MindFox supports manually created tasks and tasks proposed by AI.
Task information may include:
Creating a task manually does not require Google AI.
AI-generated task proposals are created only when AI processing is enabled.
An AI date suggestion is not automatically scheduled as a reminder.
MindFox can generate source-grounded reviews from saved memories that you select or from memories within a selected time range.
When you tap Generate review, Google AI must be enabled.
For an AI review, MindFox may send relevant information to Google Gemini through Firebase AI Logic, including:
The app may limit the number of memories or excerpt long memories to stay within processing limits.
A generated review may contain:
Generated Digests are stored locally on your device.
Digest also provides a separate Share action.
This is different from Generate review.
When you use the Digest Share action, MindFox prepares the selected saved thoughts and their current task information locally on your device.
The share can respect:
Preparing and opening this local share action does not enable Google AI and does not create a new Gemini request.
The resulting text is passed to Apple’s iOS share sheet only when you choose to share it.
Ask My Mind lets you ask questions about saved MindFox memories.
MindFox first ranks candidate memories locally.
When Google AI is enabled and you submit a question, MindFox may send Google Gemini:
The AI is instructed to answer from the MindFox source material supplied with the request.
Ask My Mind does not perform a general web search.
Ordinary search in Memories is performed locally on your device.
Local search may inspect saved information such as:
Related-memory suggestions are also determined locally using shared saved people, topics, or tags.
These local operations do not create a Gemini request.
Google AI is optional.
Before automatic AI organization is enabled, MindFox presents an AI and privacy disclosure.
The disclosure explains that:
Opening the disclosure does not by itself enable AI or send a saved thought.
AI is enabled only after you choose Enable Automatic Organization.
If you choose Not Now, MindFox continues to save and use your thoughts locally without enabling Google AI.
You can change this choice later in More → AI & privacy.
When Google AI is enabled, a newly saved thought may be sent to Google Gemini through Firebase AI Logic for organization.
Information included in an organization request may include:
Gemini may return structured information such as:
MindFox checks AI-provided supporting quotations against the saved transcript before using them as supporting evidence.
AI output may be incorrect.
MindFox preserves your original saved words so you can compare generated information against the source.
You may edit a saved transcript.
When the transcript changes, MindFox does not present an older AI interpretation as though it necessarily describes the edited text.
If you later choose Organize with AI or Re-run AI, the updated transcript may be sent to Gemini in a new request.
You can turn Automatic AI organization off.
Turning AI off:
Turning Google AI off does not automatically turn off Apple’s Speech Recognition permission.
MindFox does not send raw voice recording files to Gemini.
MindFox does not need to send an entire Mind Pack or local Digest Share export to Gemini merely because you export or share it.
Local search does not send a Gemini request.
Manually creating or editing a task does not send a Gemini request.
Preparing a backup does not send a Gemini request.
MindFox stores memories, tasks, and saved Digests locally using Apple’s SwiftData framework.
This may include:
MindFox does not require a separate developer-hosted MindFox user account to access this library.
MindFox keeps unfinished drafts locally so ordinary navigation, keyboard dismissal, or an interruption does not immediately destroy unfinished work.
Local drafts may include:
These drafts remain in MindFox’s private local application storage until saved, cleared, replaced, or deleted.
Voice recordings are stored separately from the SwiftData text library.
MindFox applies iOS file-protection options to recording files and recording metadata.
Depending on transcription status and your Keep audio after transcription preference, audio may be deleted after a successful save or retained for replay, recovery, or deliberate sharing.
MindFox can schedule optional task reminders through Apple’s local notification system.
Notification permission is requested when you choose to save a reminder and permission has not already been decided.
A local MindFox notification may contain:
MindFox provides a Hide task text in notifications preference.
When this preference is enabled, MindFox uses generic notification text instead of displaying the task content in the notification body.
MindFox reminders are local notifications.
MindFox does not sync tasks to Apple Reminders.
Nothing is automatically scheduled merely because AI suggested a possible date.
You select and save a reminder yourself.
MindFox can create Mind Packs from saved content.
The current app supports:
MindFox does not create PDF Mind Packs in the current version.
Mind Pack ranges include:
A Mind Pack may contain:
Mind Packs are assembled locally on your device from already saved content.
Creating or sharing a Mind Pack does not make a new AI request.
Audio files are not included in Mind Packs.
When MindFox creates a temporary local file for the iOS sharing workflow, it attempts to remove that temporary share file after the sharing workflow ends or is cancelled.
You may deliberately:
These operations occur only when you choose them.
Once information is passed to another app, file location, or service that you select, that destination controls its copy according to its own privacy practices.
MindFox can create a restorable JSON backup containing saved library text and data.
A backup may contain:
Audio recording files are separate and are not included in the standard text/data backup.
Restorable JSON backups are limited by MindFox to 30 MB.
MindFox backup and text export files are not password-protected by MindFox.
Store exported files only in locations you trust.
MindFox can create a plain-text export containing saved original transcripts.
This export is prepared locally and does not require a Gemini request.
You may deliberately choose a MindFox JSON backup for import.
MindFox validates the backup before import.
Import is designed to:
Importing a backup does not create device synchronization.
Saved memories, tasks, Digests, drafts, and any retained recordings remain in MindFox’s local storage until they are removed according to the app’s controls, operating-system behavior, or your settings.
Completed audio may be removed automatically when Keep audio after transcription is off.
Exported copies are controlled by the location or service to which you exported them.
You can delete individual memories.
Deleting a memory is designed to remove:
Previously exported copies are not automatically deleted.
A saved legacy Digest that does not reference the deleted memory may remain.
You can delete tasks and Digests separately.
Deleting a task cancels its associated local MindFox reminder.
Deleting a Digest does not delete its original source memories.
MindFox provides Delete all data on this device.
This operation is designed to delete:
Deleting local MindFox data does not:
Deleting the app removes information stored in MindFox’s app container from the device, subject to normal iOS backup, restore, and operating-system behavior.
Deleting MindFox does not automatically delete:
Apple provides speech-recognition technology used by MindFox.
When supported on-device recognition is required, speech processing can occur locally.
If Apple server-based recognition is used, audio may be transmitted to Apple for speech recognition.
Apple’s independent handling, protection, and retention of that information are governed by Apple’s policies.

MindFox uses Google Gemini through Firebase AI Logic for optional AI functionality.
The current MindFox code uses the Gemini Developer API provider through Firebase AI Logic.
Firebase states that Firebase AI Logic itself does not store customer input and output data sent to and received from the selected generative-AI model provider.
The selected Gemini provider’s retention and data-use rules still apply.
Google’s data-use and retention practices can depend on the developer project’s service tier and configuration.
Google currently documents that:
MindFox does not control Google’s independent retention after information has been transmitted.
MindFox does not itself use your transcript text to train a separate MindFox AI model.

MindFox uses Firebase App Check to help protect Firebase-connected AI requests against unauthorized clients.
Production builds use:
These services may process technical app/device attestation information and tokens needed to verify that a request originates from an authentic app or supported device.
MindFox does not use these security signals to build a profile of the content of your thoughts.
Firebase’s and Apple’s independent handling of security and attestation information is governed by their applicable policies.
When you deliberately share, export, save, or import information, MindFox may use Apple system interfaces such as:
The destination or source you select may be managed by Apple or another third-party service.
MindFox does not control copies of information after you deliberately export or share them outside the app.
On supported versions of iOS, MindFox exposes App Intents that can be used through Apple system features such as Siri and Shortcuts to start or finish a recording.
Apple controls the Siri and Shortcuts system environment and may process interaction information under Apple’s own privacy practices.
Using these entry points does not change MindFox’s treatment of the resulting recording, transcript, or saved memory.
If you deliberately contact MindFox support, the information you choose to include in your message is processed by the email services involved.
MindFox does not automatically attach your notes or recordings to a support email.
Any third party that processes user data for MindFox provides the same or equal protection of user data as stated in this policy and as required by Apple’s App Review Guidelines.
MindFox shares information with third parties only for the functions described in this policy and subject to the choices and permissions described above.
MindFox does not:
MindFox is designed around local storage and user-controlled processing.
MindFox uses Apple’s application sandbox and iOS file-protection mechanisms for applicable local files.
MindFox uses Firebase App Check with Apple App Attest or DeviceCheck to help protect Firebase-connected AI requests.
Exported files and standard MindFox backups are not password-protected by MindFox.
Once you export or share information, protect the destination appropriately.
No storage or transmission method can be guaranteed to be completely secure.
You can:
Turning AI off stops future MindFox Gemini requests but cannot recall information already transmitted to Google.
Revoking Speech Recognition permission affects future speech-recognition requests but does not recall information already processed by Apple.
MindFox is not directed to children under 13.
We do not knowingly collect personal information from children under 13.
We may update this Privacy Policy from time to time.
