Kinsef ("Kinsef", "we", "us") is a personal budgeting app. This policy explains what information the app collects, how it's used, and how you can request it be deleted.
Account information. When you create an account, we collect your email address and a password (stored securely, hashed, by our authentication provider — we never see or store your raw password). If you don't create an account, the app still assigns you an anonymous identity so your data has somewhere to live; this identity is not tied to any personal information until you choose to create an account.
Financial data you enter. Kinsef stores the budget data you type into the app yourself: category and subcategory names, income and expense amounts, dates, notes, and credit-card budget labels you create (e.g. a spending limit you set for "My Visa"). We do not connect to your bank or card accounts, and we never collect real account numbers, card numbers, or balances from any financial institution — every figure in the app is one you entered by hand.
Advertising data. Free-tier use of the app shows ads served by Google AdMob. Google may collect an advertising identifier and other device/usage data to serve and measure ads, as described in Google's Privacy Policy. We don't control what Google collects for this purpose beyond the settings AdMob exposes to us.
Purchase data. If you buy a Pro or Pro+ subscription, the purchase is processed by Google Play Billing and managed through RevenueCat, who provide us with your subscription status and entitlement (active/expired/plan) so the app can unlock the right features. We do not receive or store your payment card details — those stay with Google Play.
We do not sell your personal information, and we do not use your financial data for advertising targeting.
We use the following service providers (sub-processors) to run the app:
Each only receives what it needs to do its job. We don't share your data with anyone else, and we never sell it.
We keep your account and financial data for as long as your account exists. To request deletion of your account and all associated data, email support@kinsef.app from the email address associated with your account. We'll delete your data within 30 days of a verified request.
Your data is protected in transit (HTTPS/TLS) and at rest, and access to it is restricted to your own household by database-level security rules — no one, including us, can read another household's data through the app's normal operation.
Kinsef is not directed at children under 13, and we do not knowingly collect information from them.
If this policy changes, we'll update the date at the top of this page.
