Delete My Data
CertusFX works without an account, and your preferences stay on your device. If you created an account, this page explains exactly what we store and how to have it permanently deleted.
What we store
•
Your account email address and an encrypted password (authentication is managed by Supabase).
•
What gives you access — when your free trial started, your lifetime unlock or early-user date, and any pass with its expiry date — and a record of each purchase (the store or Stripe transaction reference, the product and its dates), if you bought one.
•
Nothing else is stored with your account: base currency, language, watchlists and alerts live on your device, not on our servers. Our server logs can include your account ID for purchases and refunds, as the Privacy Policy describes.
How to delete your account and data
1.
Email support@nestcalc.ai from the email address you use to sign in to CertusFX.
2.
Use a subject like "Delete my account" — no reason or explanation is required.
3.
We will confirm and permanently delete your account within 30 days. The records of your purchases and refunds are kept for refunds and for our tax and accounting records, without your email address or any other account detail: they keep only the random account ID and the store or Stripe transaction reference they were recorded under.
Deletion removes your sign-in, your profile and the access record on it — including a lifetime unlock bought on the web and tied to your account, which is removed with it. A lifetime unlock bought in the iOS or Android app belongs to your Apple or Google account and restores through that store. Deletion does not cancel anything — the lifetime unlock and passes are one-time purchases with no recurring billing. Store purchase history stays with Google Play or the App Store, and payment records for purchases made on the web stay with Link and Stripe, under their own policies. Crash reports and usage statistics from the iOS and Android apps are not linked to your account; Google Firebase removes them on its own — crash reports after 90 days, usage statistics after 14 months.
Never created an account?
Then we hold nothing you entered in the app — preferences, watchlists and alerts live only on your device. Our hosting layer keeps minimal technical logs of site visits, and the iOS and Android apps send crash reports and basic usage statistics to Google Firebase under an app identifier rather than your account. If you bought on the web without an account, we keep a record of that purchase with one-way hashes of its code and of the email you gave at checkout, and Stripe keeps its record of the payment. If you bought in the iOS or Android app without an account, started the free trial there, or had the app installed before the update that brought the one-time unlock, we keep that record (the store transaction reference, the product and its dates, or the trial or early-user date) under the app’s anonymous purchase identifier, not under any personal data. All of this is described in the Privacy Policy.
Rates are reference values for information only, not dealing quotes.
