Privacy Policy

Arthly is private by design and ad-free. Here's exactly how we handle your data.

Effective date: 7 September 2026

1. Our approach

Your financial data is personal. Arthly is built so that your data is used only to power the features you see in the app. We do not sell your data, and Arthly is ad-free.

2. Information we collect

Receipt photos stay on your device. Receipt images you attach to an expense are stored locally on your phone and are never uploaded to our servers.

3. How we use your information

We do not use your data to build advertising profiles, and we do not use it to assess your creditworthiness or for any lending purpose.

3a. Smart parsing and third-party AI

Arthly first tries to read transaction text using its own pattern rules, which run entirely on our servers. Anything the rules cannot interpret can optionally be passed to Anthropic, a third-party AI provider, purely to extract the amount, date, merchant and transaction type.

3b. Google user data

Arthly's use and transfer of information received from Google APIs adheres to the Google API Services User Data Policy, including the Limited Use requirements. Gmail data is used only to provide the statement-import feature visible in the app. It is never sold, never used for advertising, and never used to determine creditworthiness or for lending purposes.

4. Family sharing & visibility

When you share an account with family, members you invite can see the balance and transactions of that shared account, with each transaction attributed to the person who recorded it. Your personal (unshared) accounts and categories remain private to you.

5. Data storage & security

Your data is transmitted securely and protected with industry-standard safeguards. The app also offers biometric lock for an added layer of protection on your device. While no method of transmission or storage is 100% secure, we work to protect your information using reasonable technical and organizational measures.

6. Data sharing

We do not sell your personal data and we do not share it for advertising. We share data only with service providers who process it on our behalf, under agreements that protect your information, or where required by law. Those service providers are:

6a. Analytics and crash diagnostics

We use Google Analytics on this website and on the web version of the app to understand which pages and features are used, so we know what to improve. It is not used for advertising, and we have disabled Google's advertising and remarketing signals.

We also use Firebase Crashlytics in the mobile app. When the app crashes it sends a diagnostic report — the error, the stack trace, the device model and OS version — so we can fix it. Reports are linked to your account ID, but never to your name, email or phone number, and financial values are stripped from the report before it leaves your device.

7. Your rights

7a. Data retention

We keep your data for as long as your account is active. When you delete your account it is erased immediately — there is no deactivation period — and routine encrypted backups rotate out within 30 days. We retain nothing further except where a legal or regulatory obligation requires it.

8. Children's privacy

Arthly is not directed to children under 13, and we do not knowingly collect data from them.

9. Changes to this policy

We may update this policy from time to time. Material changes will be reflected by updating the effective date above.
