Private by design

Privacy Policy

Manticore Finance is built to keep your financial data on your own machine. There is no account, no login, and no analytics or telemetry collected by the app.

Last updated: 15 August 2026
The short version. Your finances — holdings, balances, budgets, net worth — live in a local file on your device, which you can encrypt with a passphrase. The app has no user accounts and sends no usage data to us. The only network requests it makes are to public market-data providers, to fetch the prices you ask it to display. Even your licence is verified offline — nothing phones home. We never see your portfolio.

1. Who this covers

This policy explains how the Manticore Finance desktop application ("the app") and this marketing website handle information. It is written for the way the app actually works today; where the app and the website differ, each is addressed separately below.

2. Data stored on your device

Everything you enter into the app — watchlist symbols, portfolio quantities and cost basis, income and expenses, budgets, wallet balances, liabilities, net-worth history, scenarios, and settings — is stored locally on your computer, in your operating system's user-data folder. It is not uploaded to us or to any server we control.

Because there is no cloud copy, you are responsible for your own backups. The app can export a portable backup file at your request; that file is written to a location you choose and is never transmitted anywhere.

3. No account, no telemetry

The app has no sign-up, login, or user account. It does not contain analytics SDKs, advertising trackers, crash-reporting beacons, or any mechanism that reports your usage back to the Licensor. We do not build a profile of you and have nothing to sell to third parties, because we do not collect it in the first place.

4. Third-party market data

To show live prices, charts, currency conversions and market sentiment, the app requests public data directly from third-party providers over the internet. Those requests are made from your device to the provider, and can include the identifiers needed to fulfil them — for example the ticker symbols or coin IDs on your watchlist, and the currency codes you view in. This is the information needed to look up a price; your holding quantities, cost basis, balances and other personal figures are not part of these requests.

When your device contacts these providers, their own privacy policies and terms apply to those requests (they may, like any web service, log the requesting IP address). We do not control and are not responsible for their practices. The stock/crypto Fear & Greed composite is computed locally on your device — nothing about your portfolio is sent to compute it.

Your own provider key (optional). You can paste your own free CoinGecko Demo API key under Settings → Data providers to raise your rate limit. That key is stored locally with the rest of your data and is sent only on your own requests to CoinGecko, as a request header — never to us. Your relationship with that provider, including their terms, pricing and usage limits, is solely between you and them. Leave it blank to stay on the shared free tier.

Bonds are entered by hand. No free feed prices a bond by ISIN, so bond details are values you type in yourself. They stay on your device and are not sent to any data provider.

5. Licensing — verified offline

Manticore Finance requires a purchased licence key. That key is verified entirely on your own machine using an Ed25519 signature — there is no activation server, no licence check over the network, and nothing that phones home. We receive no telemetry, no install pings and no usage signal when you run the app.

One thing worth knowing: a licence names its buyer, and that name appears in the app's title bar and in the footer of any PDF report it exports. That is deliberate — it makes a leaked copy traceable — so treat your key and your exported reports as identifying you.

6. Buying and licence delivery

Buying is the one part of Manticore Finance that involves your personal data, so it is set out here in full. None of it touches the financial data in the app, which never leaves your device.

7. Encryption & security

You can set a passphrase in the app to encrypt your local data file with AES-256-GCM, using a key derived from your passphrase via the memory-hard scrypt function. With encryption on, the file is unreadable ciphertext without the correct passphrase. There is no recovery mechanism and no backdoor: if you lose the passphrase, the data cannot be recovered by us or anyone else. Please keep it safe and keep backups.

8. This website

This marketing website does not use advertising or cross-site tracking cookies, and asks you for no personal information. Every asset it needs — fonts, scripts, images — is served from this domain, so rendering the page makes no request to any other party.

Optional email updates. If you choose to enter your email address in the sign-up on our free-tools pages, we use it for one purpose only: to email you when we release a new free tool or a Manticore Finance update. The lawful basis is your consent — you tick a box and then confirm through a link we email you (double opt-in), and we keep a record of that confirmation. Your address is stored and the emails are sent through Resend, our mail provider; it is never sold, shared, or used for anything else. Every update email carries a one-click unsubscribe, and you can ask us to erase your address at any time (see Section 10). We keep it only until you unsubscribe.

9. Children

Manticore Finance is intended for adults managing their own finances and is not directed to children under 16. We do not knowingly collect information from children.

10. Your rights

Your financial data. It stays on your device and we hold no copy, so you already have full control: you can view, edit, export, or permanently delete all of it directly in the app at any time. There is nothing for us to hand over or erase, because there is nothing here.

Your purchase record. The order and licence details in Section 6 are the one thing we do hold. If you are covered by the GDPR or a similar law you may ask us for a copy of it, ask us to correct it, or ask us to erase it — erasure being subject to the accounting records we are legally required to keep. Contact us using the details below; if you are unhappy with how we respond you may complain to your national data-protection authority, which in Belgium is the Gegevensbeschermingsautoriteit / Autorité de protection des données.

11. Changes to this policy

We may update this policy as the app evolves. Material changes will be reflected here with a revised "last updated" date. Continued use of the app after an update constitutes acceptance of the revised policy.
