Privacy Policy

Last updated: July 11, 2026

tracknfo ("the app") is a subscription and free-trial tracker built to work entirely on your device. This policy explains what data the app uses, what it doesn't, and how the small number of third-party services it relies on are involved.

Local-first: your data stays on your device

tracknfo has no account system, no sign-up, and no backend server of its own — there is no online account to create at any point. All the subscriptions, categories, and settings you enter are stored locally on your device using on-device storage. We do not collect, transmit, or have access to this data. If you export a backup file, it is saved to a location you choose and shared only through the share method you pick — it is never sent to us.

Because there is no cloud sync, your data does not automatically transfer between devices or survive a reinstall. If you plan to reinstall the app, switch phones, or clear the app's storage, export a backup first (Settings → Export) so you can import it again afterwards — otherwise the data is lost.

Permissions the app uses

• Notifications — used only to remind you locally before a free trial you've logged converts to a paid charge. These reminders are scheduled on your device; no notification content is sent to any server.
• Biometric authentication (Face ID / fingerprint) — an optional app lock you can enable in onboarding or Settings. Your biometric data is handled entirely by your device's operating system; the app never sees or stores it.
• Network access — used for two things: (1) fetching current currency exchange rates from a public rates API (open.er-api.com) so multi-currency totals convert correctly, cached on your device for 12 hours; and (2) validating a one-time purchase (see below). Neither use transmits your subscription data.

In-app purchases

tracknfo offers an optional one-time "Pro" unlock. Purchases are processed by Google Play Billing and validated using RevenueCat, a purchase-management service. When you make a purchase, Google and RevenueCat process the transaction and confirm your entitlement back to the app — we do not receive or store your payment details, which are handled entirely by Google Play. See RevenueCat's privacy policy and Google's privacy policy for details on how each service handles data.

Third-party services this app uses

• open.er-api.com — public currency exchange rate data (no personal data sent).
• RevenueCat — purchase validation and entitlement management for the Pro unlock.
• Google Play Billing — payment processing for the Pro unlock.

tracknfo does not use analytics, advertising, or tracking SDKs of any kind.

Legal basis for processing (GDPR)

Where EU/EEA data protection law (GDPR) applies, the limited processing described above relies on the following legal bases under Article 6 GDPR:

• Performance of a contract — processing your purchase through Google Play Billing and RevenueCat is necessary to provide the Pro unlock you're paying for.
• Legitimate interest — the currency-rate lookup is used to make the app's conversion feature work correctly, with no profiling or tracking involved.

We do not rely on consent as a legal basis because we do not collect personal data directly — your subscription and settings data never leaves your device.

International data transfers

RevenueCat and Google Play Billing may process purchase-related data on servers located outside the EU/EEA (including in the United States). Where this occurs, these providers rely on their own safeguards, such as Standard Contractual Clauses, to ensure an adequate level of protection. See their respective privacy policies linked above for details.

Data retention

Since tracknfo does not operate a backend, there is no server-side retention period for your subscription data — it exists only on your device for as long as you keep the app installed, or until you delete it yourself. Purchase records related to the Pro unlock are retained by Google Play and RevenueCat per their own retention policies, as needed to maintain your entitlement and for legal/accounting obligations.

Your rights under GDPR

If GDPR applies to you, you have the right to:

• Access the personal data we hold about you
• Request correction of inaccurate data
• Request erasure of your data
• Restrict or object to processing
• Request data portability
• Lodge a complaint with a supervisory authority

Because tracknfo does not collect or store personal data on any server, most of these requests can be satisfied simply by deleting the app or its data from your device. For anything related to the purchase records held by Google Play or RevenueCat, you can also contact those providers directly, or reach us at info@tracknfo.com and we'll help route the request.

If you are in the Slovak Republic, the relevant supervisory authority is:

Úrad na ochranu osobných údajov Slovenskej republiky
Galvaniho Business Centrum II, Galvaniho 7/B
821 04 Bratislava, Slovak Republic
Tel.: +421 2 3231 3214
Email: statny.dozor@pdp.gov.sk
Web: www.dataprotection.gov.sk

If you are elsewhere in the EU/EEA, you may lodge a complaint with your own local data protection authority instead.

Children's privacy

tracknfo is not directed at children and does not knowingly collect any information from children, since it does not collect personal information from any user in the first place.

Changes to this policy

If this policy changes — for example, if a new feature introduces a new data use — this page will be updated and the "Last updated" date above will change accordingly.
