This Privacy Policy applies to Tfc-nm ("the App"), the NFT profit-and-loss calculator published under the name Tfc-nm on Google Play. In this Privacy Policy, "we," "our," and "us" refer to the developer responsible for Tfc-nm.
Tfc-nm helps users estimate profit and loss on NFT mints and flips, compare marketplace fees, and track a portfolio of positions.
The App's calculations run locally on your device using JavaScript. No account registration or login is required. We do not operate a backend server that receives or stores your calculator entries or saved portfolio positions.
This Privacy Policy explains how information is processed when you use Tfc-nm, what may be stored on your device, and how you can contact us.
Information you enter into Tfc-nm, including prices, fees, quantities, and portfolio positions, is processed locally on your device. We do not receive, store remotely, or have access to these entries.
During normal use of the calculator:
You are not required to provide your name, email address, or other contact information.
We do not collect cryptocurrency wallet addresses or blockchain transaction information.
Calculator entries are not transmitted to a server operated by us.
We do not use the calculator to collect device identifiers or precise location information.
Requests for third-party resources may involve technical information, including your IP address, as described in Section 4. If you contact us by email, we receive the information you choose to send, as described in Section 10.
Certain features of Tfc-nm may store information locally on your device using browser storage, such as localStorage. This may include saved portfolio positions and display preferences, such as light or dark mode.
Locally stored information:
Remains in the local storage used by the App on your device.
Is not uploaded or synchronized with our servers.
Is not shared by us with third parties.
May remain until you delete it or clear the relevant local storage.
May be deleted when you clear the browser or site data associated with Tfc-nm.
May not be available in private or incognito browsing.
Will generally not transfer when you switch browsers or devices.
You may delete saved positions within Tfc-nm where that functionality is available, or remove locally stored information by clearing the browser or site data associated with Tfc-nm.
Because we do not receive your locally stored calculator or portfolio information, we cannot access, recover, or delete it remotely.
Tfc-nm does not use cookies for tracking purposes and does not include advertising, behavioral analytics, or third-party tracking scripts.
The App may load fonts, including IBM Plex Mono and Public Sans, through Google Fonts. When your browser requests these resources, technical information, including your IP address, may be transmitted to Google to deliver the resources. This is separate from your calculator entries, which are processed locally.
Information processed by Google in connection with these requests is subject to Google's privacy policy:
https://policies.google.com/privacy
Apart from such resource requests, Tfc-nm does not intentionally transmit information you enter into the calculator to third parties.
Tfc-nm may display marketplace fee percentages or other reference information relating to third-party services, including OpenSea, Blur, Magic Eden, LooksRare, and X2Y2.
These figures are provided for informational and convenience purposes and may be editable within the App. Mentioning a marketplace does not, by itself, mean that Tfc-nm sends your calculator entries or portfolio information to that marketplace.
Tfc-nm is an independent application and is not affiliated with, sponsored by, endorsed by, or officially connected with any referenced NFT marketplace, cryptocurrency wallet provider, blockchain network, or other third-party service unless expressly stated otherwise.
Marketplace fees and other costs may change and may vary by collection, transaction, account, marketplace, or region. Users should verify current fees and terms directly with the applicable service.
Tfc-nm is not directed to children and is not intended for use by anyone under the age of 13, or any higher minimum age required by applicable laws in the user's jurisdiction.
We do not knowingly collect personal information from children. If you believe a child has provided personal information to us, including by email, please contact us using the details in Section 10 so we can review and address the matter.
Calculator entries and saved portfolio information are processed or stored locally on your device. We do not maintain a centralized user database containing this information.
The security of locally stored information depends on your device, browser, operating system, and related settings. You can manage or remove locally stored information as described in Section 3.
You should keep your device and browser secure and avoid allowing unauthorized access to locally stored information.
Tfc-nm is provided solely for general informational, educational, and planning purposes.
Nothing provided through Tfc-nm, including profit or loss calculations, break-even estimates, gas fee estimates, or marketplace fee comparisons, constitutes financial, investment, legal, accounting, or tax advice.
Cryptocurrency, blockchain, and NFT transactions may involve significant risks. Actual transaction costs, marketplace fees, gas fees, taxes, asset values, and other expenses may differ from estimates displayed by the App.
You should independently evaluate relevant information and consult an appropriately qualified professional before making financial, investment, legal, or tax decisions.
We may update this Privacy Policy to reflect changes to Tfc-nm, our practices, or applicable requirements.
The revised policy will be published with an updated "Last updated" date at the top of this page. Because Tfc-nm does not require an account or contact information, we do not maintain a user contact list for individual update notifications.
Please review this Privacy Policy periodically.
If you have questions, concerns, or requests regarding this Privacy Policy or Tfc-nm's privacy practices, contact the developer responsible for Tfc-nm at:

If you contact us by email, we receive your email address and any information you choose to include in your message. We use this information to respond to your inquiry and handle related privacy requests. Email correspondence is separate from the calculator information stored locally on your device.
