Knoddex ("we", "our", or "us") operates the Calqy - Note Calculator mobile application (the "App").
This Privacy Policy explains what information we collect, how we use and store it, how your data is synchronized between your device and our servers, and how certain third-party services used by the App may process information.
By using Calqy - Note Calculator, you agree to the collection and use of information in accordance with this Privacy Policy.
We collect information necessary to provide, maintain, synchronize, secure, and improve the functionality of the App.
When you create an account, we may collect:
Full Name
Email Address
Date of Birth
Password
Your email address and password are used for account registration, authentication, and login.
Your date of birth may be used as part of the account verification and password recovery process.
When signing in, you provide:
Email Address
Password
We use this information to authenticate your account and provide access to your saved data.
Calqy allows you to create notes and perform calculations within those notes.
The information you create may include:
Note text
Mathematical calculations
Calculation results
Note creation date
Note last-edited or updated date
This information may be stored locally on your device and synchronized with our servers when an internet connection is available.
Calqy is designed to work both online and offline.
When you use the App without an internet connection, your notes and related data may be stored in a local database on your device.
This allows you to continue creating, editing, and using your notes and calculations while offline.
Local data may include:
Notes
Calculations and results
Creation dates
Modification dates
Information required to manage synchronization
When your device reconnects to the internet, eligible locally stored information may automatically synchronize with your account on our server.
Removing or uninstalling the App may result in the deletion of locally stored information that has not yet been synchronized with the server.
When you are signed in and an internet connection is available, your notes and related information may be uploaded and stored on our hosting/server infrastructure.
Cloud synchronization allows you to:
Keep your notes backed up
Access synchronized information across sessions
Restore synchronized notes after signing in
Continue working offline and synchronize changes later
Keep locally stored and server-stored information updated
The App communicates with our servers through secure APIs to store, retrieve, update, and synchronize your information.
Synchronization may occur automatically when an internet connection becomes available.
We may use the information collected through Calqy to:
Create and manage your user account
Authenticate users
Provide sign-in and sign-up functionality
Support password recovery
Create, save, and manage notes
Perform and store calculations within notes
Store notes locally for offline use
Synchronize notes with our servers
Restore synchronized information
Maintain the functionality and reliability of the App
Identify application crashes and technical problems
Understand general App usage and improve performance
Protect the App and our services from misuse or unauthorized access
We do not intentionally use the contents of your private notes for advertising purposes or to create advertising profiles.
Calqy may use Firebase Crashlytics, a service provided by Google, to identify crashes, errors, and technical problems within the App.
Crashlytics may automatically collect technical information such as:
Device type and model
Operating system information
App version
Crash logs
Diagnostic information
Device or installation identifiers
Information about the state of the App when a crash occurs
We use this information to diagnose problems, improve stability, and maintain the reliability of the App.
Calqy may use Google Analytics for Firebase to better understand how users interact with the App.
Analytics information may include:
App usage information
App version
Device information
General interaction events
Session information
Technical identifiers
General performance information
We use analytics information to understand overall App usage, identify areas for improvement, and improve the user experience.
Calqy does not intentionally request or collect the following types of information:
Precise GPS location

SMS messages
Call history
Payment card information
Banking information
Advertising identifiers for personalized advertising
Biometric information
Health information
Microphone recordings or audio data
The App does not intentionally collect these types of information unless a future version introduces functionality that requires such information.
If App functionality changes in the future and additional personal information or permissions become necessary, this Privacy Policy may be updated accordingly.
We take reasonable technical and organizational measures to protect information stored through Calqy.
This may include measures designed to protect data while it is transmitted between the App and our servers and to restrict unauthorized access to stored information.
However, no method of electronic storage, internet transmission, or cloud storage can be guaranteed to be 100% secure.
Users are responsible for keeping their account credentials confidential and should not share their password with others.
We do not sell your notes or account information.
We may share or allow processing of limited information when necessary:
With service providers that help us operate and maintain the App
With Google services used for crash reporting and analytics
When required by applicable law or a valid legal request
When necessary to protect our rights, users, systems, or services from fraud, abuse, or security threats
Third-party services only receive information according to their respective functions, configurations, policies, and legal requirements.
We do not use Google advertising services to display personalized advertisements within the App.
We may retain your account information and synchronized notes for as long as your account remains active or as necessary to provide the App's services.
Locally stored information remains on your device until it is:
Deleted by you
Removed by the App
Cleared through your device settings
Removed when the App is uninstalled
Server-stored information may remain until it is deleted according to our account deletion and data retention processes.
Some technical, security, diagnostic, or legally required records may be retained for a limited period where reasonably necessary.
You may request deletion of your account and associated personal information.
To request account or data deletion, contact:
Email: knoddex@gmail.com
Please contact us using the email address associated with your Calqy account when possible so that we can verify the request.
After verification, we may delete your account information and associated synchronized data, subject to information that we are legally required or reasonably permitted to retain.
Deleting your cloud account may not automatically remove information that remains locally stored on another device. Local information may need to be removed separately from the device or App.
Calqy is not intended for children under the age of 13.
We do not knowingly collect personal information from children under 13.
If we become aware that personal information has been collected from a child under 13 without appropriate authorization, we will take reasonable steps to delete that information.

Core note-taking and calculation functionality may continue to work offline using the App's local database.

These may include:
Analytics-related preferences
App permissions
Network and internet access
Disabling certain functionality may affect some features of the App.
Our servers and third-party service providers may process or store information in countries other than the country in which you live.
Where required, we take reasonable steps to use services and safeguards appropriate for the processing of personal information.
Third-party providers such as Google may process information according to their own global infrastructure and privacy practices.
We may update this Privacy Policy from time to time to reflect:
Changes to the App
New functionality
Changes to third-party services
Security improvements
Legal or regulatory requirements
When changes are made, the updated Privacy Policy will include a revised effective date.
Significant changes may also be communicated through the App, website, App Store, Google Play listing, or another appropriate method.
