Optimizer

Privacy Policy

Last updated 19 July 2026

This policy explains what personal data Fiscalance collects, why, how long it is kept, and the rights you have over it. Fiscalance is a tool for freelancers and one-person companies (BV) to model tax optimizations; this policy covers the Fiscalance website and account, not the tax advice you get from your own accountant.

Who is the data controller

Fiscalance (“we”, “us”) is the data controller for personal data processed through fiscalance.com. For any privacy question or to exercise your rights, contact us at [email protected].

What data we collect

Account data: your email address and (if you set one) a display name, created when you sign up.

Business and financial figures you enter into the optimizer: day rate, billable days, business expenses, director salary, planned dividends, VAPZ/IPT contributions, and similar inputs used only to compute your optimizations. If you save a profile to your account, these figures are stored against it; if you use the tool without an account, they stay in your browser only.

Billing data: if you subscribe, Stripe (our payment processor) handles your card details directly — we never see or store your full card number. We keep a record of your subscription status, plan and renewal date so the app can unlock your report.

Technical data: standard server logs (IP address, browser user agent, timestamps) kept briefly for security and abuse prevention.

Why we process it (lawful basis)

To provide the service you asked for (contract): creating your account, running the optimizer, and unlocking paid features.

To meet legal obligations (legal obligation): keeping billing records for accounting and tax purposes.

With your consent, where required: for example, functional cookies/localStorage beyond what is strictly necessary, or optional analytics if enabled (see our Cookie Policy).

Legitimate interest: keeping the service secure and preventing abuse of the free tier or API.

Stripe as a processor

We use Stripe, Inc. to process subscription payments. Stripe acts as our processor for payment data and has its own privacy policy governing how it handles your card details. We only receive the minimum data needed to manage your subscription: a customer ID, subscription status and renewal date.

How long we keep your data

Account and profile data is kept for as long as your account is active. If you delete your account, your profile, business figures and subscription record are deleted from our database immediately; Stripe retains billing records as required by law for its own accounting obligations.

Server logs are kept for a short rolling window (typically a few weeks) and then discarded.

Your rights

Under the GDPR you have the right to access, correct, export and erase your personal data, and to object to or restrict certain processing.

Access & export: use “Download my data” on your Account page to receive a copy of the account, profile and subscription data we hold on you, in a machine-readable format.

Erasure: use “Delete account” on your Account page to permanently delete your account, business details and subscription record. This cannot be undone.

If you would rather not use the in-app tools, email [email protected] and we will action your request. You also have the right to lodge a complaint with the Dutch Data Protection Authority (Autoriteit Persoonsgegevens).

Cookies

Fiscalance uses only an essential session cookie (to keep you signed in) and functional browser storage (to remember your inputs and preferences). See our Cookie Policy for the full list, including any optional analytics.

Changes to this policy

We may update this policy as the service evolves. The “last updated” date at the top of this page reflects the latest revision.
