You can delete your Spendly account and all associated data at any time. This page explains both ways to do it, as required by Google Play's account-deletion policy.
Fastest: inside the app
Open Spendly → Settings → Delete account → enter your password and type DELETE. Access is revoked immediately on all devices and your data is permanently erased within 30 days. You can export everything first from Settings → Export my data.
Without the app
Email support@joinspendly.com from the address you registered with, subject "Account deletion request". We verify ownership and complete deletion within 30 days, confirming by reply.
What gets deleted
Everything: your profile, transactions, wallets, categories, budgets, goals, receipt images, preferences, and analytics events tied to your account. Store subscription billing records are retained by Apple/Google under their own policies; cancel any active subscription in your store settings (deleting your account does not cancel store billing — the stores require you to do that in their interface).
