Privacy

Last updated: October 19, 2026

How Cherry Valley Consulting LLC (“StarPenta,” “we,” “us”) handles information when you use starpenta.com, request free or Plus-trial study authorization, or complete a purchase or contribution.

Short version

• We do not sell your personal information.
• We collect what we need to run the site, answer email, entitle or revoke Sierra Chart studies (free and Plus trial), and fulfill Stripe purchases or contributions.
• Never send us your Sierra Chart account password. Any site passphrase is separate and should be unique.
• Card payments are handled by Stripe; we do not store your full card number.

Who we are

• Controller: Cherry Valley Consulting LLC
• Contact: hello@starpenta.com
• Website: starpenta.com

What we collect

• Email you send us - address and message content when you contact hello@starpenta.com, support@starpenta.com, or similar.
• Study entitlement (free and Plus trial) - Sierra Chart username (primary identifier); email address for confirmation links; a passphrase you choose (stored only as a one-way hash); pending one-time tokens; trial end / consumed markers where applicable; date/time of requests; approximate technical metadata such as IP address (hashed) for abuse prevention.
• Purchases and contributions - from Stripe webhooks and our fulfillment records: Sierra Chart username you entered at checkout, email Stripe provides (if any), amount, currency, livemode flag, payment / session identifiers, product type (for example Plus vs Free Supporter), and fulfillment status. Stripe processes card details under its own privacy policy; we do not receive or store full card numbers.
• Server and security logs - standard hosting logs (for example Cloudflare, Fly.io) may include IP, user agent, URL, and timestamps.
• Fonts / CDN - this site may load fonts from Google Fonts or similar; those providers may receive your IP and browser data under their own policies.

Why we collect it

• Respond to inquiries and deliver product help you asked for.
• Authorize, trial-limit, or remove studies against your Sierra Chart username via Sierra’s published mechanisms.
• Verify cancel/remove requests using the passphrase you set.
• Fulfill paid Plus unlocks and Free Supporter contributions (Service Level / EndDate updates).
• Limit abuse (for example excessive entitlement attempts from an IP).
• Operate, secure, and improve the website and related services.

How we store and share

• Entitlement and payment ledger records may be stored in a database we control (for example MongoDB Atlas) and processed by our application hosts (for example Fly.io for access email flows; Cloudflare Workers for Stripe webhooks).
• Sierra Chart receives the username (and whatever else their authorization API requires, such as Service Level or EndDate) so the study can load for that account; that sharing is required for entitlement to work.
• We use processors that help us host email (for example Resend), payments (Stripe), DNS, and the site (for example Cloudflare Pages). They process data on our instructions or as independent controllers for their services (Stripe for cards).
• We may disclose information if required by law, to protect rights and safety, or in connection with a business transfer of the LLC.

Passphrases

• Choose a unique passphrase (not your Sierra password, not a password you reuse elsewhere). Eight or more characters when we enforce a minimum.
• Store it in a password manager or other safe place. We cannot email you the original passphrase if we only store a hash.
• If you forget it, contact us; we may require enough information to believe you control the Sierra username before removing or resetting entitlement.
• See also the Terms (Authorization).

Retention

• Email: kept as long as needed to handle your request and ordinary business records.
• Active entitlement records: while you remain authorized or as needed to enforce one-trial / abuse rules, then deleted or anonymized within a reasonable period after cancel/revoke (unless we must keep a minimal abuse/audit trail).
• Payment / contribution records: kept as long as needed for accounting, tax, dispute, and fulfillment history.
• Security / rate-limit logs: short periods (for example days to weeks) unless investigating abuse.

Cookies and analytics

• The marketing site is primarily static. We do not currently run a third-party ad pixel.
• Our host (e.g. Cloudflare) may set strictly necessary cookies or collect edge analytics.
• Stripe Checkout may set cookies required to complete payment on Stripe-hosted pages.
• If we add optional analytics later, we will update this page.

Children

• The site and studies are aimed at adults who use professional trading software. We do not knowingly collect data from children under 13 (or under 16 where that is the relevant age).

Your choices

• Use the site cancel/remove flow when available (Sierra username + passphrase) for free or trial access.
• Email hello@starpenta.com to ask what we hold about your Sierra username, to correct it, or to request deletion where applicable (payment records may need to be retained).
• Depending on where you live (e.g. EEA/UK/California), you may have additional rights; tell us your location when you write and we will work through reasonable requests.

Changes

• We may update this Privacy page; the “Last updated” date will change. Material changes to entitlement or payment data practices will be reflected here.
