DRAFT — pending review by the owner and a lawyer.

Privacy policy

Last updated: October 31, 2026 (draft).

What we collect

• Wallet addresses you enter. A Solana address is public. We use it to fetch that wallet's public transaction history and calculate the results you see. We keep the fetched public transaction data in a cache to make repeat lookups faster, and keep recent results in memory for about 15 minutes.
• Your email, only if you join the list. We store the email address, when you joined, and the exact consent text you agreed to.
• Abuse-prevention data. To enforce rate limits we store a one-way salted hash of your IP address with a daily counter. We do not store your IP address itself.
• Your review answers (costs you enter, transfers you mark as sales or gifts) are stored in your own browser (localStorage). They are sent to our server only to recalculate your results and are not kept there.
• We do not use advertising trackers or analytics cookies. Our hosting provider (Cloudflare) processes requests to deliver and protect the site and may set strictly necessary security cookies.

What we never collect

Private keys, seed phrases, wallet connections or signatures. Do not send them to anyone.

How we use it

To run the calculator, to email you about the exports you asked to hear about (and occasional product updates you agreed to), and to keep the service from being abused. Every email will include a way to unsubscribe.

Sharing

We do not sell or share your personal information, and we do not share it for cross-context behavioral advertising. Service providers that host or deliver the service (Cloudflare; a future email delivery provider) process data on our behalf.

Your choices and rights

You can ask us to delete your email or tell you what we hold about you. California residents have rights under the CCPA/CPRA, including the right to know, delete and correct personal information and to not be discriminated against for using them. [Contact email to be added once a support address exists.]

Retention

List emails are kept until you unsubscribe or ask for deletion. Rate-limit counters are kept for a short period. Cached public blockchain data is pruned automatically.

Children

The service is not directed to children under 13 (and is intended for adults who file US taxes).

Changes

We will update the date above when this policy changes.
