Introduction
Slofi ("we", "our", or "us") is a personal finance application that helps you record transactions, manage a balance sheet, and view analysis charts. This Privacy Policy explains what information we collect, how we use it, and the choices you have.
By using Slofi, you agree to this policy. If you do not agree, please do not use the app.
Information We Collect
Account information: your email address and authentication identifiers from Supabase Auth (including sign-in via Google when you choose that option).
Profile information: an optional display name you set in Settings.
Financial data you enter: transactions (dates, amounts, categories, descriptions, notes, tags), balance sheet items and monthly snapshots, recurrence rules, and related metadata.
Billing data: if you subscribe to Premium, Stripe processes payment details. We receive billing-related identifiers such as customer and subscription ids, plan status, and the email used at checkout. We do not store full card numbers on Slofi servers.
Technical data: standard logs from our hosting providers for security and operations, such as IP address and request timestamps when you use the service.
How We Use Your Information
We use your data to provide the Slofi service: storing your records, showing charts and summaries, importing and exporting CSV files you request, processing Premium subscriptions, and keeping your account secure.
We do not sell your personal information. We do not use your financial data for advertising.
Where Data Is Stored
Your app data is stored in a PostgreSQL database hosted by Supabase. Row Level Security ensures each user can only access their own rows. Authentication is handled by Supabase Auth.
Payment processing for Premium is handled by Stripe. Card data is collected and stored by Stripe under their terms.
Sharing With Third Parties
We share data only with service providers needed to run Slofi. That currently includes Supabase for database and authentication, Google when you sign in with Google OAuth, and Stripe when you purchase or manage a Premium subscription. Those providers process data under their own terms and privacy policies.
We may disclose information if required by law or to protect rights, safety, and security.
Data Retention and Deletion
We retain your data while your account is active. You may delete your account from Settings by confirming with the phrase shown on the delete-account screen. Deletion removes your auth user and associated app data from our database (subject to backup retention by our host for a limited period).
If you have an active Premium subscription when you delete your account, we cancel renewal at the end of the current paid period so billing does not continue after your account is gone. Stripe may retain payment records as required for their own compliance.
Your Choices
You can update your display name, export your data as CSV, and sign out at any time. Email/password users can change their password in Settings.
Premium subscribers can manage or cancel renewal through the Stripe customer portal linked from Account settings.
To stop using Slofi, delete your account as described above or contact us if you need assistance.
Security
We rely on Supabase authentication, HTTPS, and database Row Level Security. No method of transmission or storage is 100% secure. Use a strong password and protect your device.
Children
Slofi is not directed at children under 13 (or the minimum age in your jurisdiction). We do not knowingly collect data from children.
Changes to This Policy
We may update this policy from time to time. We will post the revised version in the app and update the "Last updated" date.
