Overview

Bitcoin Stack Lab is a Bitcoin planning web app. It helps users maintain a manual Bitcoin planning balance, view live BTC price estimates, use planning tools and LTV scenarios, save goals and projections, and use backups and account access. Parts of the app can be used while signed out. Signed-in users can use account features such as cloud backup.

Information we collect

Bitcoin Stack Lab collects or stores only information needed to provide the app features you use. This may include:

  • Account information such as your email address, user ID, and authentication session details when you sign in.
  • App data you enter, such as your planning profile, selected currency, LTV loan setups, goals, projections, settings, and backup data.
  • Feedback or contact messages you submit through the app.
  • Technical data required to run the app, such as browser, device, session, network, diagnostic, or hosting-provider data handled by the services that operate the app.

Information users must not enter

Bitcoin Stack Lab does not need wallet secrets and will not ask you for them. Do not enter:

  • Seed phrases or recovery phrases.
  • Private keys.
  • Wallet passwords or exchange passwords.
  • Bank login details.
  • Two-factor recovery codes.
  • Signing details or wallet approval instructions.
  • Any other sensitive secret that could give someone access to your funds, accounts, or identity.

How information is used

Information is used to:

  • Provide the app, account access, and saved app data.
  • Calculate manual-stack valuations and planning estimates.
  • Provide cloud backup, cloud restore, and file-backup features.
  • Send requested feedback, support messages, or alert emails when those features are enabled.
  • Improve reliability, troubleshoot issues, and protect the app from misuse.

X Pixel and advertising measurement

With your consent, Bitcoin Stack Lab uses the X Pixel for campaign attribution and advertising measurement. X may process general browser, device, and activity information generated by the pixel. Bitcoin Stack Lab temporarily keeps only allowed UTM attribution fields in the current browser session to carry attribution through authentication redirects; it does not retain a raw URL or other query parameters. Bitcoin Stack Lab does not intentionally send wallet addresses, balances, transactions, loan amounts, seed phrases, or other financial portfolio data to X. It also does not send email addresses, account identifiers, profile names, or other enhanced-conversion identifiers to X. You can decline tracking in the Tracking preferences prompt without affecting the app, or withdraw/change your choice later using the Tracking settings button shown in the app.

Local storage, cloud storage, and backups

Some app data may be stored locally in your browser. Signed-in users may save and load app backup data using cloud storage. File export and import features let you create and restore your own backup files. You are responsible for storing exported backup files safely, because they may contain transaction, profile, and planning data. Clearing browser data, replacing a cloud backup, or importing the wrong file may affect what data is available in the app.

Third-party services

Bitcoin Stack Lab uses third-party services to operate current app features. These may include:

  • Supabase for authentication, cloud app data, backup records, and feedback records.
  • Resend for app emails, such as feedback notifications and LTV risk alert emails when enabled.
  • CoinGecko for live and historical BTC price data used by the app.
  • X for consent-based campaign attribution and advertising measurement through the X Pixel.
  • The app hosting provider for serving the website and processing technical data needed to keep it running.

Historical records

Some historical application and billing records may be retained for backup, security, operational, or legal reasons. Retention and deletion requests are handled in accordance with the applicable process.

Data security

Authentication is handled through the auth provider, and app data is protected using reasonable technical safeguards for the features provided. No system can guarantee absolute security. You should protect your account access, keep exported backup files private, and never enter wallet secrets, seed phrases, private keys, or passwords into Bitcoin Stack Lab.

Access, correction, and deletion

You can contact Bitcoin Stack Lab to ask about account data, correction, or deletion. Requests may require verification and may not be completed instantly. Some records may need to be retained for security, troubleshooting, legal, backup, or operational reasons.

Overseas disclosure and third-party processing

Some service providers used to operate Bitcoin Stack Lab may process or store data outside Australia. Bitcoin Stack Lab relies on those providers to operate authentication, hosting, cloud storage, email, and related app services.

Children

Bitcoin Stack Lab is not intended for children. If you are under the age of majority in your location, use the app only with appropriate parent or guardian involvement.
