Privacy Policy for Lumentime

Last Updated: August 23, 2026

Introduction

Colored Pixels Studio built the Lumentime app as an Ad Supported app, with an optional ad-free Pro upgrade. This SERVICE is provided by Colored Pixels Studio and is intended for use as is.

Throughout this document, “Colored Pixels Studio,” “we,” “our,” or “us” refers to the individual owner/developer operating under the brand name “Colored Pixels Studio” and any affiliated parties who contribute to the development, maintenance, or operation of the Lumentime app. These terms protect both the brand name “Colored Pixels Studio” AND the individual developer personally from ANY and ALL liability, claims, damages, or legal actions.

This page is used to inform visitors regarding our policies with the collection, use, and disclosure of Personal Information if anyone decided to use our Service.

If you choose to use our Service, then you agree to the collection and use of information in relation to this policy. The Personal Information that we collect is used for providing and improving the Service. We will not use or share your information with anyone except as described in this Privacy Policy.

The terms used in this Privacy Policy have the same meanings as in our Terms and Conditions, which is accessible at Lumentime unless otherwise defined in this Privacy Policy.

Information Collection and Use

Lumentime does not require you to create an account, sign in, or provide any personal information to use the app. We do not operate any server of our own and we do not store your personal data on any online server of ours. Certain third-party services used by the app (advertising and purchase management) may collect limited technical information as described below. Separately, if you voluntarily choose to send us feedback by email from within the app, that email will contain technical information about your device as described in the “Optional In-App Feedback” section below.

App Configuration Data

To provide the core functionality of our app, we store your lamp configurations and settings locally on your device. Lamp configurations are stored in an on-device SQLite database, and app preferences are stored using your device’s standard local preference storage. This information includes:

Lamp color preferences and brightness settings
Timer configurations and auto-dimming preferences
Display mode selections (LED, Neon, Glass, Full screen, etc.)
Custom text for neon displays
Ambient sound selections
Flow mode and animation preferences
Device brightness control settings
App preferences such as theme, sound and haptic settings, and onboarding and tutorial completion status
A local record of when the app was first set up, how many times a lamp has been switched on, and whether a review prompt has already been shown, used solely to decide when to display an optional review request
A local flag recording the result of the most recent successful online Pro purchase check, so that Pro features continue to work when your device is offline

Important Information About App Data:

All lamp configurations and app preferences are stored locally on your device only
We do not upload or sync your lamp data to any remote server
We do not track your usage patterns or lamp preferences
Your settings and configurations remain private to your device
All data processing occurs on your device
You can delete all data by uninstalling the app
NO CLOUD BACKUP OR SYNC: We do not provide cloud backup, account sync, or cross-device synchronization of your lamp data
NO LOGIN REQUIRED: We do not collect usernames, passwords, email addresses, or any login credentials
NO USER ACCOUNTS: The app functions entirely without user account creation or personal identity verification
LOCAL DATA ONLY: If you uninstall the app, clear app data, or reset your device, all your lamp configurations will be permanently lost and cannot be recovered by us or by anyone else
NO LIABILITY FOR DATA LOSS: We accept no responsibility whatsoever for the loss, corruption, or unavailability of any data stored on your device, regardless of cause

Free vs Pro User Features

Lumentime offers different feature sets for free and Pro users. Understanding these differences is important for your usage expectations:

Free Users Receive:

A maximum of 2 custom lamps
Full Lamp display mode only
Basic timer functionality
A limited set of basic ambient sounds
Full screen mode access with ads
Advertisement-supported experience
The ability to preview Pro display modes and Flow Mode within the lamp settings screen; saving a lamp that uses a Pro feature requires a Pro purchase

Pro Users (One-time purchase) Receive:

Unlimited custom lamps
All lamp display modes (LED, Neon, Glass, Full Screen)
Advanced auto-dimming features
Flow mode with breathing light effects
All ambient sounds including Pro sounds
Ad-free experience
Full screen mode without advertisements

Feature availability, limits, and pricing may change at any time and may differ between app versions, platforms, and regions.

Internet Connection Requirements

Different parts of the app have different connectivity requirements:

Free users require an active internet connection to use the app. Because the free version is advertisement supported, the app will display a “no internet connection” screen and will not be usable while your device is offline
Pro users can use the app offline. After your Pro purchase has been confirmed online at least once, the app stores a local flag on your device recording that result, allowing Pro features to continue working without a connection
This offline flag is stored only on your device, is never transmitted to us, and is updated whenever the app is next able to verify your purchase status online
If you install the app on a new device while offline, the app will be unable to confirm your Pro purchase until an internet connection is available

Device Permissions

The app may request or use the following device capabilities. None of the data involved is collected, transmitted, or stored by us:

Screen Brightness Control — used only to adjust your device’s display brightness to match your lamp settings when you enable this optional feature
Audio Playback — used only to play ambient sounds within the app
Notifications — used only for timer and app-related alerts, where supported
Network Access — used only to load advertisements and to verify Pro purchase status

Device Brightness Control

When you enable device brightness control features in the app:

The app may adjust your device’s screen brightness to match lamp brightness
This setting is entirely optional, is off unless you enable it, and can be disabled at any time
No brightness data is collected or stored beyond your current session
Brightness adjustments only occur while the app is actively being used

BY ENABLING THIS FEATURE YOU DO SO VOLUNTARILY AND ENTIRELY AT YOUR OWN RISK. COLORED PIXELS STUDIO ACCEPTS NO LIABILITY WHATSOEVER FOR ANY EYE STRAIN, VISION PROBLEMS, HEADACHES, MIGRAINES, SEIZURES, PHOTOSENSITIVE REACTIONS, DIZZINESS, NAUSEA, SLEEP DISRUPTION, OR ANY OTHER HEALTH EFFECT, NOR FOR ANY BATTERY DRAIN, OVERHEATING, SCREEN BURN-IN, PIXEL DEGRADATION, DISPLAY DAMAGE, HARDWARE MALFUNCTION, REDUCED DEVICE LIFESPAN, OR ANY OTHER DAMAGE TO YOUR DEVICE ARISING FROM OR RELATED TO THIS FEATURE.

Pro Purchase and Payment Processing

Our app offers a one-time Pro purchase that removes advertisements and unlocks premium features. For purchase management we use RevenueCat, a third-party service that handles purchase validation and customer identification. When you purchase Pro access:

RevenueCat creates an anonymous customer identifier to manage your Pro status
Your purchase is processed through your device’s app store (Google Play Store or Apple App Store)
RevenueCat tracks your Pro status and entitlements to ensure proper access to Pro features
Pro status is synchronized across your devices using the same app store account
The app stores the result of the most recent successful online verification locally on your device so that Pro features remain available while offline
We do not handle or store payment information directly — all payment processing is managed by Google Play or the Apple App Store
NO PERSONAL LOGIN DATA: We do not collect or store your Google account credentials, Apple ID information, name, email address, or any payment card details
APP STORE ACCOUNT ONLY: Pro status is tied solely to your app store account (Google Play or Apple ID) — we have no access to your account information
AUTOMATIC VERIFICATION: Pro status verification occurs automatically through your device’s app store without requiring any login information from you

However, the app does use third party services that may collect information used to identify you.

App Review Prompts

From time to time the app may invite you to rate or review Lumentime. There are two kinds of prompt, and both are optional — you are never required to leave a review, and declining has no effect on any app feature:

Store review prompt: After you have been using the app for a period of time, the app may display your device’s standard, operating-system-provided review prompt. This prompt is presented entirely by Apple or Google, not by us. We do not receive any information about whether you saw it, dismissed it, or submitted a rating, and we cannot link any review to you
Developer message: The app may display an in-app message from the developer inviting you to leave a review or send feedback. This message contains a photograph of the developer and a short personal note. Choosing “Leave a Review” opens your device’s app store listing. Choosing “Maybe Later” dismisses it

To decide when to show these prompts, the app keeps a small number of counters on your device only — for example how long ago the app was set up, how many times a lamp has been switched on, and how many prompts have already been shown. These counters never leave your device, are never sent to us, and contain no personal information. Your device’s operating system may also independently limit how often review prompts can be displayed.

Optional In-App Feedback

Please read this section carefully, as it describes the only circumstance in which information is sent directly to us.

The developer message described above includes a “Send Feedback” option, and the app’s menu contains a similar feedback option. If you choose to use it, the app will open your device’s email application with a pre-filled draft message addressed to us. Before sending, that draft will contain technical information intended to help us diagnose issues, which may include:

Whether your account has Pro status or is a free account
If you are a Pro user, the anonymous RevenueCat customer identifier associated with your purchase
The app version and build number
Your device platform, operating system version, screen dimensions, and screen pixel density
The date and time the message was generated

Important points about this feature:

ENTIRELY VOLUNTARY: Nothing is sent unless you choose to open the feedback option and then choose to send the email yourself. Simply having the app installed sends us nothing
YOU CAN SEE AND EDIT IT FIRST: The information is placed in a draft email that you can read, edit, or delete before sending. If you do not wish to share any part of it, you may remove it or close the draft without sending
YOUR EMAIL ADDRESS: If you send the message, we will receive your email address, along with anything you write, as an ordinary consequence of you emailing us
THE REVENUECAT IDENTIFIER: This is an anonymous identifier generated by RevenueCat. It is not your Apple ID, Google account, name, or email address. We use it only to look up the status of a purchase when investigating a support issue you have raised
HOW WE USE IT: Information you send us by email is used solely to respond to your message, investigate the issue you have reported, and improve the app. We do not use it for advertising, we do not sell it, and we do not share it with third parties except where necessary to resolve your issue or where required by law
HOW LONG WE KEEP IT: Feedback emails are retained in our email account for as long as reasonably necessary to handle your enquiry and to keep a record of support history. You may ask us to delete your correspondence at any time by writing to the address at the end of this policy

Advertising

Our app includes advertisements provided by Google AdMob, AppLovin, Facebook Audience Network (via AdMob mediation), and other advertising partners. These advertisements are shown only to free users, as Pro users enjoy an ad-free experience. These advertisements:

When Advertising Consent Is Requested

Advertising and consent are handled as follows:

Consent and tracking prompts are presented when the app is first opened, before the introductory screens, so that no advertisement is requested until your choices have been recorded
No advertisement is requested from any advertising partner until the consent process has completed and, where consent is required, you have provided it
Pro users are not shown advertisements and no advertising requests are made for them

Apple App Tracking Transparency (iOS)

On iOS devices, the app may present Apple’s App Tracking Transparency prompt
Your device’s advertising identifier (IDFA) is only accessible to our advertising partners if you allow tracking
If you decline, you will still see advertisements, but they will not be personalized based on your interests
You can change this choice at any time in your device settings

GDPR and EU User Consent

For users in the European Union and other regions where consent is required, we implement Google’s User Messaging Platform to comply with GDPR requirements:

When you first open the app, you’ll see a consent dialog asking for permission to use your data for personalized advertising
You can choose to accept or decline personalized ads
If you decline, you’ll still see ads, but they won’t be personalized based on your interests
You can change your consent choices at any time through the “Ad Privacy Options” in the app’s settings section
Your consent choice is stored locally on your device and applies only to this app
Pro users do not see ads regardless of consent choices

Facebook Audience Network:

Our app may display ads from Facebook’s Audience Network through Google AdMob mediation
Facebook may collect and use device identifiers, usage data, and other information to serve personalized ads
Facebook may combine this information with data from your Facebook account if you have one

Any such information is used solely for the purpose of delivering advertisements, validating purchases, and maintaining app functionality.

Cookies

Cookies are files with a small amount of data that are commonly used as anonymous unique identifiers. These are sent to your browser from the websites that you visit and are stored on your device’s internal memory.

This Service does not use these “cookies” explicitly. However, the app may use third party code and libraries that use “cookies” to collect information and improve their services. You have the option to either accept or refuse these cookies and know when a cookie is being sent to your device. If you choose to refuse our cookies, you may not be able to use some portions of this Service.

We want to inform users of this Service that these third parties may have access to certain technical information about your device. The reason is to perform the tasks assigned to them on our behalf. However, they are obligated not to disclose or use the information for any other purpose.

Data Security

We value your trust in providing us your Personal Information, thus we are striving to use commercially acceptable means of protecting it. But remember that no method of transmission over the internet, or method of electronic storage is 100% secure and reliable, and we cannot guarantee its absolute security.

We implement appropriate technical and organizational measures to protect the security of your personal information. However, please be aware that no method of transmission over the internet or electronic storage is 100% secure. While we strive to use commercially acceptable means to protect your personal information, we cannot guarantee its absolute security.

On-Device Storage: All lamp configurations, timers, sound selections, and settings are stored locally on your device and are never uploaded to us. The security of data stored on your device depends entirely on your device, its operating system, and your own security practices. We accept no responsibility for unauthorized access to, loss of, or corruption of data stored on your device.

Email Correspondence: If you contact us by email, including through the app’s optional feedback feature, that message travels over ordinary email infrastructure which we do not control and which is not encrypted end to end. Please do not include sensitive personal information in any message to us.

We have no control over and assume no responsibility for the content, privacy policies, or practices of any third-party sites or services.

Children’s Privacy

These Services do not address anyone under the age of 13. We do not knowingly collect personally identifiable information from children under 13 years of age. As we do not operate any server and do not collect personal information, we hold no such data; if we become aware that a child under 13 has provided personal information through any third party service used by the app, we will take reasonable steps to have it removed. If you are a parent or guardian and you are aware that your child has provided personal information, please contact us so that we will be able to do necessary actions.

App Purpose and Comprehensive Health & Safety Disclaimers

CRITICAL WARNING – READ BEFORE USE:

RELAXATION AND AMBIANCE TOOL ONLY: Lumentime is designed exclusively as a relaxation and ambient lighting tool for sleep, focus, and mood enhancement. It is NOT intended as a medical device, therapeutic treatment, emergency lighting, safety equipment, or professional lighting solution.
COMPREHENSIVE HEALTH WARNINGS: Use of this app may cause serious health issues including but not limited to: eye strain, headaches, migraines, sleep disruption, circadian rhythm disruption, photosensitive epileptic seizures, dizziness, nausea, visual disturbances, dry eyes, blurred vision, neck and shoulder pain from poor posture, fatigue, anxiety, restlessness, and worsening of existing medical conditions. Individuals with epilepsy, seizure disorders, migraine disorders, autism spectrum disorders, ADHD, anxiety disorders, sleep disorders, depression, or any light sensitivity conditions should consult medical professionals before use.
ANIMATED AND PULSING LIGHT EFFECTS: Certain features, including Flow Mode and its breathing light animation, produce continuously changing brightness and moving light effects. Animated, pulsing, or flickering light can trigger photosensitive epileptic seizures, migraines, dizziness, nausea, or visual discomfort in susceptible individuals, including people with no prior history of such reactions. Discontinue use immediately and consult a medical professional if you experience any adverse reaction.
DEVICE DAMAGE AND SCREEN BURN-IN WARNING: Prolonged use of this app, especially at high brightness levels or for extended periods, may cause permanent and irreversible damage to your device including: screen burn-in, pixel degradation, LCD/OLED panel damage, premature display aging, color distortion, permanent ghosting, overheating, battery degradation, reduced battery life, system instability, hardware malfunction, and complete device failure. Static images displayed for extended periods are particularly likely to cause permanent screen burn-in that cannot be repaired. We accept no liability whatsoever for any such damage.
DEVICE BRIGHTNESS CONTROL RISKS: The brightness control feature is optional and is enabled solely at your discretion. When enabled, the app adjusts your device’s screen brightness which may cause: device overheating, battery drain, reduced device lifespan, eye damage from sudden brightness changes, temporary or permanent vision problems, discomfort in dark environments, sleep disruption from blue light exposure, seizures or photosensitive reactions, and interference with your device’s automatic brightness sensors. You enable and use this feature entirely at your own risk and we accept no liability of any kind for its effects.
PROLONGED USAGE DANGERS: Extended use of bright screen displays may lead to: computer vision syndrome, digital eye strain, dry eye syndrome, blurred vision, double vision, color perception changes, temporary or permanent vision loss, disrupted sleep patterns, insomnia, dependency on artificial light for relaxation, reduced natural melatonin production, and increased risk of macular degeneration.
SOUND THERAPY DISCLAIMER: While our app includes ambient sounds designed for relaxation, these are not intended as medical treatment for sleep disorders, anxiety, tinnitus, hearing loss, or other health conditions. Prolonged exposure to audio may cause hearing damage, tinnitus, auditory fatigue, or worsen existing hearing conditions. Consult healthcare professionals for medical concerns.
TIMER FUNCTIONALITY LIMITATIONS: The timer feature is designed for convenience and relaxation routines only. It should NEVER be relied upon for critical time-sensitive activities, medical timing, emergency situations, cooking timers, medication reminders, wake-up alarms, safety applications, or as a replacement for medical timers or alarms. Timer accuracy may be affected by device performance, background restrictions, power saving modes, and system factors.
NOT A MEDICAL DEVICE: This app is not intended to diagnose, treat, cure, or prevent any medical condition. It should not be used as a substitute for professional medical advice, diagnosis, treatment, light therapy, sleep therapy, or any medical intervention. Do not use this app if you have been advised by medical professionals to avoid bright lights or screens.
AGE AND SUPERVISION WARNINGS: This app is not recommended for children under 13 years old. Children and teenagers may be more susceptible to screen-related health issues, eye damage, and sleep disruption. Parental supervision is strongly recommended for users under 18.
ENVIRONMENTAL AND SITUATIONAL RISKS: Do not use this app while driving, operating machinery, in situations requiring full attention, in environments where screen light could pose safety risks, during power outages as emergency lighting, or in professional settings where color accuracy is critical. The app should not be used as a replacement for proper room lighting, reading lamps, or safety lighting.
BATTERY AND ELECTRICAL SAFETY: Prolonged use may cause excessive battery drain, device overheating, and potential fire hazard. Monitor your device temperature during use and discontinue if the device becomes excessively hot. Charging while using the app intensively may increase overheating risks.
NETWORK AND CONNECTIVITY: Advertisement loading and Pro feature verification require internet connectivity. The free version of the app requires an active internet connection in order to be used. Network issues may cause app malfunction, unexpected behavior, inability to use the free version, or data usage charges from your carrier.
INDIVIDUAL VARIATION DISCLAIMER: Effects and reactions to light therapy, relaxation apps, and screen exposure vary greatly between individuals. What works or is safe for one person may be harmful to another. Age, health conditions, medications, genetics, and environmental factors all influence individual responses.

BY USING THIS APP, YOU ACKNOWLEDGE THAT YOU UNDERSTAND THESE EXTENSIVE RISKS AND USE THE APP ENTIRELY AT YOUR OWN RISK. COLORED PIXELS STUDIO AND THE INDIVIDUAL DEVELOPER ACCEPT NO RESPONSIBILITY WHATSOEVER FOR ANY HEALTH ISSUES, INJURY, DEVICE DAMAGE, DATA LOSS, FINANCIAL LOSS, OR OTHER PROBLEMS OF ANY KIND THAT MAY RESULT FROM YOUR USE OF THIS APPLICATION.
