This Privacy Policy explains how personal information is processed when you use BrighterTwist or contact us about the app.
BrighterTwist uses Apple Private Cloud Compute to create personalised stories and suggest moods. Your story library and app preferences are stored locally, with optional iCloud synchronisation. The app does not display advertising, and you do not need to create a BrighterTwist account.
1. Who is responsible for your information
BrighterTwist is provided by SPECTRUMSPARKS LTD, company number 14997439, whose registered office is 128 City Road, London, United Kingdom, EC1V 2NX. We are the controller of personal information where we determine why and how it is processed.
You can contact us about privacy matters at info@spectrumsparks.co.uk or through the SpectrumSparks contact page.
This policy applies to BrighterTwist and related support enquiries. It does not cover other SpectrumSparks products. Apple’s own services and any services you choose to use when sharing content are also subject to their respective privacy notices.
2. Apple Private Cloud Compute
BrighterTwist uses Apple Private Cloud Compute when you ask it to create or continue a story or suggest a mood. You choose whether to include personal details using the persistent Personalisation setting. Onboarding offers “Personalise my stories” to turn it on or “Try a story first” to leave it off. You can change it later in Settings, below Terms. With it off, new stories use planned characters and plot without your personal setup details; Apple Private Cloud Compute is still used. Choosing a route or editing your draft does not by itself send a story-generation request.
For a personal story request, BrighterTwist uses the information you enter or select for that story. This can include character names and details, a chosen mood, optional thoughts, selected journal text, place and activity descriptions, previous story content and your continuation choices. The app may derive writing guidance from those details to shape tone, pacing and energy.
Story generation
To generate or continue a story, the information needed for your request is sent securely to Apple Private Cloud Compute for processing. This includes relevant descriptions and derived writing guidance, as well as personal information contained in the text and details you choose to include.
Apple states that request content processed by Private Cloud Compute is used only to fulfil the request, is not made accessible to Apple and is not retained by Private Cloud Compute after processing. Apple separately describes limited operational information and optional device analytics in its Apple Intelligence & Privacy notice.
Selected workout and activity descriptions, mood-based writing guidance, thoughts and journal text may be included in model requests. That text can contain or reveal health-related information. Raw journal images, audio and other attachment files, and step-count values held in activity attachments, are not included in those model requests. Information you type yourself can still contain measurements or other personal details.
Mood suggestions
You can ask BrighterTwist to suggest a mood based on your optional written thought. The suggestion is applied only if you choose to accept it. Your accepted or manually selected mood then influences the story’s tone and writing style.
Mood suggestions are processed by Apple Private Cloud Compute. The written thought you submit for this feature is sent to that service to generate the suggestion.
Stories may contain personal information from your inputs. Review generated content before sharing it or enabling its synchronisation.
3. Information processed by the app
Information you provide
BrighterTwist processes the details you enter or select, including:
- Character names, gender or pronoun choices
- Story world, mood, language and reading preferences
- Optional thoughts and reflections
- Selected journal moments and related text
- Story content, continuation choices and drawings
You can use fictional character names and omit optional information. Only include personal information about other people where you are entitled to do so.
Information from selected journal moments
If you use Apple Journaling Suggestions, the app imports the moments you select. These may include names, places, dates, songs, podcasts, activities and local previews of related content.
Selected photo, video, contact and artwork previews are stored and displayed locally. The attachment files themselves are excluded from story-generation requests and iCloud story copies. Reflection prompts can help you choose what to write; any text you include in your thought may be sent when you request a mood suggestion or a personal story.
The app does not browse your entire address book or maintain a general location history.
App activity and preferences
The app stores information needed to maintain your library and settings, including unfinished stories, saved stories, reading progress, reading duration, reading days, streaks and reminder preferences.
Derived personalisation information
BrighterTwist uses the mood you select or accept and the activity descriptions you choose to derive guidance for story tone, pacing, energy and themes. Mood suggestions are based on your written thought. Selected activity descriptions can influence features such as physical energy or persistence within the story.
Selected context, mood choices and derived personalisation state are stored locally with story setup and progress. These are creative personalisation cues and may not accurately reflect how you feel.
4. Optional connections and Apple services
Selected journal moments, activity and mood
BrighterTwist uses selected moments from Apple Journaling Suggestions, including workout and activity descriptions, to personalise the tone, pacing, energy and writing of your stories. It also uses the mood you choose, or a mood suggestion you accept based on an optional written thought.
Relevant activity descriptions and derived writing guidance may be included in requests to Apple Private Cloud Compute, as described in section 2. Your own thoughts or journal text may also contain health-related information. Excluding raw measurements does not exclude these descriptions or inferences.
Activity and place details come from the individual Journaling Suggestions you choose, rather than from the app reading a health database, querying motion sensors or collecting your current location. Journaling Suggestions is optional and adding new selected moments requires Personalisation to be on. You can enter story details manually instead; these personal details are used for model requests only while Personalisation is on. Only content included in the selected suggestion is available to the app; choosing a suggestion does not give the app general access to your journal, contacts or photo library.
You can remove a selected moment from your draft before requesting a story. Choosing moments or editing the draft does not itself ask Apple Private Cloud Compute to generate a story. A selected photo may trigger the separate Apple Maps lookup described below.
Photo locations
When a selected photo includes location metadata, BrighterTwist may use it to identify the city or country associated with that photo. The coordinates are rounded to approximately kilometre precision and sent to Apple Maps for this lookup.
The app does not retain those coordinates or include them in story-generation requests. The resulting city or country name may be saved and used to personalise a story. See Apple Maps & Privacy for information about Apple’s service.
iCloud synchronisation
iCloud sync is off until you enable it in Settings. Enabling it sends completed stories, unlocked epilogue text and associated library information to your private iCloud database so they can be synchronised across your devices. This is a separate choice from including personal details in a story. Earlier sync settings do not replace the current sharing choice.
The synchronised information includes story titles and text, dates, story-world and progress information, epilogues, and records needed to synchronise deletions. Completed prose may contain personal or health-related details from the information you chose, even though raw setup information is excluded.
Unfinished stories, raw setup information, journal attachments and separate epilogue-generation context are excluded from these cloud copies. The app also uses an iCloud account identifier to detect account changes. If your iCloud account changes, you must enable sync again.
Apple states that private CloudKit content is not visible to the developer through its developer portal. See Apple’s private CloudKit documentation.
Turning sync off stops future syncing but does not delete existing iCloud or local copies. A request already submitted cannot be recalled. Section 8 explains the available deletion controls.
Siri, Shortcuts and system search
Siri discovery is off until you make a separate sharing choice in Settings. Enabling it shares story titles and full prose with Apple’s system discovery and this device’s protected Spotlight index. Saved prose may contain personal or health-related details. An earlier indexing setting does not grant this new choice.
A protected local index may include story titles, text, dates, story worlds and current questions or choices. Raw journal attachments, raw setup details and attachment measurements are not indexed separately, although indexed story text may reflect personal details and personalisation.
Turning discovery off removes the app’s indexed entries and stops automatic discovery. An already submitted system request cannot be recalled. Siri or Shortcut actions you deliberately invoke can still access, display or speak the story content required to carry out your request. You can also manage Siri access in your device settings.
Siri and Shortcuts story-generation actions respect the same Personalisation setting. With it off, new stories exclude personal setup details, and continuing an existing personal story is paused until you turn it back on. Generic stories still use Apple Private Cloud Compute. Reading or speaking a saved story you request remains available.
BrighterTwist’s narration feature does not record microphone audio. Siri and dictation may process speech under Apple’s separate Siri, Dictation & Privacy notice.
5. Purchases, diagnostics and support
Purchases
Purchases are processed by Apple through the App Store. BrighterTwist uses purchase and entitlement information supplied by Apple to provide purchased features and restore access. The app does not receive your payment-card details.
Apple’s processing is described in App Store & Privacy.
We do not download or retain Apple sales reports or customer receipts outside Apple’s systems.
Diagnostics
The app records local technical information, such as generation status and purchase errors, to support troubleshooting. It does not include third-party analytics or crash-reporting software.
Apple may process system diagnostics and analytics according to your device settings and its privacy notices.
We do not download or retain Apple crash reports outside Apple’s systems.
Support
When you contact us, we receive your email address, message and any attachments or other information you provide. We use this information to respond to your enquiry, resolve problems and handle privacy requests. Our email service is provided through GoDaddy, which processes these communications on our behalf.
Please limit what you send to information relevant to your enquiry. You do not need to send your full story library or journal.
6. Purposes and your choices
BrighterTwist processes information to carry out the actions you request: creating and continuing stories, suggesting a mood, maintaining your local library and preferences, verifying purchases, synchronising or sharing content when you choose, and answering support enquiries.
Personalisation: the choice is saved on this device. “Personalise my stories” turns it on during onboarding; “Try a story first” leaves it off. You can turn it on or off at any time using Personalisation in Settings, below Terms. With it on, relevant names, mood, thoughts and selected moments can shape stories through Apple Private Cloud Compute.
When Personalisation is off: new stories use planned characters and plots through Apple Private Cloud Compute without your stored personal names, mood, thoughts, selected moments or cached personal story context. Mood suggestions and adding new Journaling Suggestions are unavailable. Further generation, translation, mood updates and bonus epilogues for an existing personal story are paused until you turn Personalisation back on. You can still read your saved stories.
Keeping your information: turning Personalisation off keeps your draft details and saved stories; it does not erase or rewrite them. Turning it back on allows relevant retained details to be used in later personal requests. You can edit or remove details and use the deletion controls in section 8. Turning it off stops subsequent personal requests and prevents pending personal work from continuing; a request already sent for processing cannot be recalled.
Before sending a personal request: you can choose a mood yourself, omit the optional thought, edit character details and remove selected journal moments. A mood suggestion sends the written thought only when Personalisation is on and you ask for it; accepting the suggested label is a separate choice.
Separate sharing choices: iCloud synchronisation and Siri discovery have their own Settings controls, described in section 4. Turning either off stops the corresponding future automatic sharing; it does not change the content of saved stories or the other setting. Exports and Siri actions you deliberately request can still disclose the content needed for that action.
Thoughts, journal text and generated prose may contain sensitive information, including information about health. Excluding raw attachments and measurements does not exclude sensitive descriptions you choose to include in text. The app’s personalisation and mood suggestions are creative features, not medical assessments, and are not used to make decisions about you with legal or similarly significant effects.
Optional information is not required for the non-personal story route. Please limit support enquiries to information needed to resolve the issue; you do not need to send a full story library or journal. Section 10 explains how to contact us about your information and privacy rights.
7. Disclosure and international processing
Information is disclosed or made available as described in this policy:
- To Apple for the model processing and platform services you use
- To GoDaddy, our email service provider, when you contact us
- To recipients and other apps you select when sharing or exporting content
- To authorities or professional advisers where disclosure of information we hold is legally required or otherwise lawfully necessary
Apple’s own processing is described in its service-specific notices and Privacy Policy. These notices are separate from our responsibilities for information we control.
Apple may process information outside the United Kingdom as described in its service-specific privacy notices.
Our email provider, GoDaddy, operates internationally, so support communications may be processed outside the United Kingdom. GoDaddy’s published Data Processing Addendum describes the safeguards it uses for applicable international transfers, including recognised adequacy arrangements and contractual safeguards for UK transfers. You can contact us for information about the safeguards applicable to your enquiry.
8. Retention and deletion
Information stored in the app
Your profile, selected journal context, mood choices, derived personalisation state, saved content and preferences remain on your device until removed through the relevant app controls or otherwise deleted. Saved stories do not have a fixed automatic expiry period.
The app provides the following controls:
- Delete a story: removes the story locally and synchronises its deletion when iCloud sync is enabled. A limited deletion record is retained to support synchronisation
- Discard an unfinished story: removes that unfinished story and its choices, and clears the current daily inputs. Saved stories remain
- Reset preferences: resets reading, language, collection and reminder settings. It does not delete stories, drawings or profile information, or disable iCloud sync
- Erase data on this device: removes local stories, unfinished content, profile and journal context, drawings, preferences and temporary app-created exports. It also disables reminders and iCloud sync
A limited record of the consumed free-preview allowance remains after in-app erasure. Purchase entitlements are managed separately.
iCloud and other copies
Device erasure does not remove existing iCloud copies, external exports, shared copies or system permissions. Turning off sync also leaves existing cloud copies in place.
To remove a synchronised story, delete it while iCloud sync is enabled and allow the deletion to complete. This removes its story content from the synchronised library. A deletion identifier remains to prevent the story from being restored during synchronisation.
The app does not currently provide a single control to erase all BrighterTwist data from iCloud. Backups and copies held by other apps or recipients must be managed separately.
Other retention
Private Cloud Compute processes request content as described in section 2. Other Apple services have their own retention arrangements.
We retain routine support correspondence, including troubleshooting information you send us, for 12 months after the enquiry is resolved. We delete personal story attachments when they are no longer needed to resolve the issue, normally when the enquiry is closed. Where particular information is needed for an unresolved dispute or a legal obligation, we retain only the information necessary for that purpose.
You can contact us if you need help identifying or deleting information for which we are responsible.
9. Security
BrighterTwist uses Apple platform protections for local storage, protected system indexing and private iCloud storage. We limit the information used by each feature as described in this policy.
No method of storage or transmission is completely secure. Protecting your device and Apple account, keeping software up to date and checking what you share also helps protect your information.
10. Your rights
Depending on applicable law and the circumstances, you may have the right to:
- Access personal information we hold about you
- Correct inaccurate information
- Request deletion or restriction of processing
- Receive certain information in a portable format
- Withdraw consent where processing relies on consent
Right to object: you may object to processing based on legitimate interests, subject to the conditions in applicable law. You may also object to direct marketing if your information is used for that purpose.
To exercise your rights, contact info@spectrumsparks.co.uk. We may request proportionate information to verify your identity and understand your request. We will respond within the applicable statutory time limits.
Where information is held only on your device or in your private iCloud storage, we may provide instructions for using the relevant controls rather than retrieve it centrally. Apple provides separate processes for information it controls.
You may complain to the UK Information Commissioner’s Office through its complaints service, or to another competent data protection authority where applicable.
11. Children’s privacy
BrighterTwist is intended for readers aged 13 and over. It is not directed at children under 13. The app does not currently verify users’ ages.
Parents and guardians can contact info@spectrumsparks.co.uk with questions or concerns about a child’s information in connection with BrighterTwist.
12. Changes to this policy
We may update this policy to reflect changes to the app, our practices or legal requirements. The revised policy will show the updated date. Where required, we will provide further notice or obtain consent before introducing relevant changes.
