MetalMetric ("we," "us," "our") operates the website at metalmetric.com and its associated services. MetalMetric is an independently owned and bootstrapped company. We built this platform as precious metals collectors ourselves, and we treat your data with the same care we'd expect for our own.
We collect only what is necessary to operate the service. Here is a complete accounting:
| Data Type | Purpose | Stored By |
|---|---|---|
| Email address | Account creation, login, transactional emails (receipts, alerts) | Clerk (authentication) |
| Name (if provided) | Displayed in your account profile | Clerk |
| Vault items & portfolio data | Storing and displaying your collection, calculating values | Neon (PostgreSQL database) |
| Payment information | Processing subscriptions (Pro, Elite) | Stripe (we never see your full card number) |
| Email subscription preferences | Sending price alerts and product updates you opted into | MailerSend |
That is the complete list. We do not collect browsing history, device fingerprints, location data, or any form of behavioral analytics beyond basic server logs (IP address, timestamp, page requested) which are automatically generated by our hosting provider and are not used for tracking or profiling.
We understand that your vault contains sensitive information about your precious metals holdings. We take this responsibility seriously.
MetalMetric employees, contractors, and automated systems do not access the contents of your vault — not for analytics, not for product development, not for marketing, and not for any other purpose.
Your vault data is stored in an encrypted database. It is read only when you request it through the application (loading your vault, calculating values, generating reports). No human at MetalMetric views this data.
The only exception: if you contact our support team and explicitly ask us to help troubleshoot a specific vault item, we may access that item with your written permission, and only for the duration needed to resolve your issue.
We believe it is important to be explicit about what we will never do with your data:
We rely on a small number of trusted third-party services to operate MetalMetric. Each is used for a specific, limited purpose:
These services process data only as necessary to provide their specific function. We do not grant any third party access to your vault data beyond what is technically required for database hosting.
All data transmitted between your browser and MetalMetric is encrypted using 256-bit TLS (HTTPS) on every request. Your vault data is stored in an encrypted PostgreSQL database with access restricted to authenticated application requests only.
Authentication tokens are issued by Clerk using industry-standard JWT (JSON Web Tokens) signed with RSA-256 keys. Payment data is handled entirely by Stripe, which is PCI DSS Level 1 certified — the highest level of payment security certification.
While no system is perfectly immune to breach, we take every reasonable precaution to protect your data. If we ever become aware of a data breach that affects your information, we will notify you promptly via the email address associated with your account.
We retain your account and vault data for as long as your account is active. If you cancel your subscription, your data remains intact — you simply revert to the free tier. Your vault items are never deleted due to a subscription change.
If you choose to delete your account entirely, we will permanently delete all associated data — including vault items, portfolio history, and personal information — within 30 days. Some data may persist in encrypted database backups for up to 90 days, after which it is automatically purged.
MetalMetric uses only essential cookies required for the service to function:
__session) — Maintains your authenticated login. Set by Clerk. Expires when your session ends.We do not use advertising cookies, analytics cookies, or any form of cross-site tracking cookies.
Regardless of where you are located, we extend the following rights to all MetalMetric users:

MetalMetric is not directed at individuals under the age of 18. We do not knowingly collect personal information from children. If we become aware that a child under 18 has created an account, we will promptly delete the account and all associated data.
If we make material changes to this privacy policy, we will notify you by email at least 14 days before the changes take effect. Minor clarifications or formatting changes may be made without notice, but the effective date at the top of this page will always reflect the latest revision.
We will never retroactively weaken your privacy protections without your explicit consent.
