Car Lease Tracker App Terms of Use

Effective date: 15 July 2026

These App Terms of Use ("App Terms") apply to Car Lease Tracker (the "App"), published by CurlyByte Solutions ("we", "us", or "our"). Please read them before using the App.

1. Agreement and Apple's Standard EULA

Before first use, the App asks you to tap “Agree & Continue”. By doing so, or by otherwise using the App, you expressly agree to these App Terms and acknowledge the Privacy Policy. The App stores the accepted Terms version and acceptance date locally on your device. These App Terms supplement, and do not replace, Apple's Standard Licensed Application End User License Agreement ("Standard EULA"), which governs the license to use the App. If these App Terms conflict with the Standard EULA on a license matter, the Standard EULA controls to the extent of that conflict. Mandatory law always remains applicable.

Read the Apple Standard EULA.

2. App purpose and informational nature

The App helps users record lease details, mileage, trips, expenses, documents, fleet usage, costs, and projections. It can also import selected vehicle data through optional connections.

The App is an organisational tool and does not provide legal, financial, tax, accounting, leasing, or contractual advice. Calculations, warnings, forecasts, extracted contract fields, reports, and expected settlements are estimates based on the information available to the App. Your signed contract and the lessor's records control. You are responsible for checking all values before making decisions or submitting them to another party.

3. Eligibility and provider accounts

You must be legally capable of agreeing to these App Terms. No Car Lease Tracker account is required for core use. Optional vehicle connections require an eligible account with the relevant provider and authority to access the connected vehicle.

You must provide accurate information, keep credentials secure, use only accounts and vehicles you are authorised to access, and comply with the provider's terms. You may disconnect a provider in the App and, where available, revoke access in the provider account.

4. Subscriptions and purchases

Some vehicle capacity, cost analytics, reports, and direct vehicle connections require a paid subscription. Available features, vehicle limits, provider connection limits, and refresh quotas depend on the selected tier.

Before the purchase action, the App states that by tapping Subscribe you agree to these App Terms and acknowledge the linked Privacy Policy. After a completed purchase, the App stores the applicable Terms version, acceptance date, selected product identifier, and resulting StoreKit transaction identifier locally on your device. Apple's purchase sheet provides the final price confirmation. By tapping Subscribe and completing the purchase, you agree that the subscription purchase and continued subscription use are governed by these App Terms and Apple's applicable purchase terms.

Apple processes purchases, renewals, cancellations, billing, and refunds under the terms shown in the App Store. We do not receive your payment card details. Manage or cancel a subscription through your Apple account settings.

5. Optional third-party vehicle connections

Vehicle connections are optional. Manual mileage tracking remains available without connecting a provider. The current connection options are:

  • Smartcar: supported brands using developer credentials supplied by you. Compatibility and provider terms are controlled by Smartcar and the vehicle manufacturer.
  • Toyota: a direct connection for supported European vehicles and eligible MyToyota accounts. Model, account, country, and service compatibility may vary.
  • Tesla: OAuth access through Tesla Fleet API for supported regions and vehicles. The App can request odometer, battery level, estimated range, vehicle identity, and related connection data, but not location. Mainland China is not supported.

Smartcar, Toyota, Tesla, MyToyota, and related names and marks belong to their respective owners. References identify compatibility only. Unless expressly stated by the relevant owner, they do not imply sponsorship or endorsement.

Providers may impose separate terms, privacy notices, subscriptions, usage charges, quotas, regional rules, or technical requirements. Those provider terms govern your relationship with the provider.

6. Connection availability and data reliability

We do not control provider systems, vehicle connectivity, or manufacturer services. We do not guarantee that any provider, account, vehicle, model, region, API, permission, or data field will remain compatible or available.

A connection or refresh may fail, be delayed, or return incomplete, stale, or inaccurate data because of provider outages, maintenance, API or policy changes, rate limits, quotas, expired or revoked authentication, account restrictions, regional limitations, poor connectivity, an offline or sleeping vehicle, manufacturer changes, backend interruption, or provider discontinuation. Providers may alter or withdraw access without notice to us.

Background refresh is scheduled by iOS and is not guaranteed to run at a specific time. Failure notifications also depend on iOS notification permissions and delivery. A displayed "connected" status does not guarantee a future successful refresh.

Always compare imported readings with the vehicle and your lessor's records. If data is missing or appears incorrect, use manual entry and contact the provider where appropriate. You remain responsible for monitoring contractual mileage and deadlines even when auto-sync is enabled.

7. Data and privacy

Core lease data is stored locally on your device. Optional provider connections exchange the data required to authenticate and retrieve the selected vehicle information. Tesla requests use our EU connection broker; Smartcar and Toyota use the connection paths described in the Car Lease Tracker Privacy Policy, which explains data categories, legal bases, retention, recipients, security measures, and your rights.

8. Your data, exports, and backups

You retain responsibility for the information you enter or import. Review exported JSON, CSV, and PDF files before sharing them because they may contain personal, contract, vehicle, mileage, or expense information. Keep appropriate backups. We cannot restore local data that is deleted, corrupted, lost with a device, or not included in an available backup.

9. Acceptable use

You must not:

  • connect an account or vehicle without authorisation;
  • circumvent provider, subscription, vehicle, connection, refresh, security, or rate limits;
  • interfere with the App, our broker, a provider API, or another user's access;
  • use the App or connection features unlawfully or in violation of provider terms; or
  • extract, probe, reverse engineer, or misuse credentials, tokens, APIs, or connection infrastructure except where applicable law expressly permits it.

10. Intellectual property

The App, its design, software, and original content are protected by applicable intellectual-property laws. Your limited right to use the App is governed by Apple's Standard EULA. You retain rights in your own records and documents.

11. Changes, suspension, and discontinuation

We may update, modify, suspend, or discontinue App features to maintain security, comply with law or provider requirements, address technical constraints, or improve the App. A provider integration may be limited or removed if continued operation becomes unavailable, unsafe, unlawful, or commercially unreasonable. Rights relating to paid subscriptions remain subject to applicable law and Apple's terms.

12. Warranties

To the extent permitted by law, the App and connection features are provided "as is" and "as available". We do not warrant uninterrupted operation, provider availability, compatibility with every vehicle or account, accuracy or timeliness of imported data, error-free calculations, or that the App will meet every individual leasing or fleet requirement. Mandatory statutory warranties remain unaffected.

13. Limitation of liability

To the extent permitted by law, we are not liable for losses caused solely by third-party provider actions or failures, unavailable or delayed connections, incorrect or stale provider data, authentication revocation, provider API changes, missed background refreshes, or your failure to verify readings. This includes, where legally excludable, indirect or consequential losses and lease overage charges based on unverified App data.

We remain liable without limitation for intent, gross negligence, injury to life, body, or health, liability under mandatory product-liability law, guarantees expressly assumed by us, and any other liability that cannot legally be excluded or limited. For slight negligence affecting an essential contractual obligation, liability is limited to the foreseeable damage typical for this type of agreement, where such a limit is permitted.

Nothing in these App Terms limits mandatory consumer rights.

14. Ending use

You may stop using the App, disconnect providers, and cancel subscriptions through Apple at any time. We may restrict connection access where reasonably necessary for security, misuse prevention, legal compliance, or provider requirements. Uninstalling the App does not itself cancel an App Store subscription or revoke access in every provider account.

15. Governing law

German law applies, excluding its conflict-of-law rules, unless mandatory law requires otherwise. If you are a consumer, this choice does not deprive you of mandatory protections available under the law of your habitual residence. Courts have jurisdiction only as provided by applicable mandatory rules.

16. Changes to these App Terms

We may update these App Terms when the App, providers, law, or business requirements change. The current version and effective date will be posted on this page. Where required, we will provide additional notice or request consent before revised terms take effect.
