Terms of Use
By installing or using the Apps you agree to these Terms. If you do not agree, do not use the Apps.
1. License grant
We grant you a personal, non-exclusive, non-transferable, revocable license to install and use the Apps on devices you own or control, for your personal or internal business use. You may not resell, sublicense, rent, or redistribute the Apps or any license token or purchased pack.
You may not: (a) reverse-engineer, decompile, or circumvent the Apps' license verification or content-signing mechanisms; (b) forge, share, or resell license tokens or packs; or (c) use the Apps unlawfully.
2. Free use and the optional "Pro" upgrade
The core calculators are available for free. We may offer an optional one-time "Pro" upgrade. When offered, Pro is:
- A one-time purchase, not a subscription. There is no recurring charge for the Pro tier.
- App-specific. A Pro purchase unlocks only the paid surfaces in the app where it was purchased. No bundle-wide pass or subscription is part of this launch.
- Delivered as a signed offline license. After a purchase is verified, you receive a redeemable key. Activation and feature unlocking happen entirely on your device and do not require an account or a network connection.
- How the key reaches you depends on the channel. On Android, Google Play delivers your entitlement automatically; use Settings > Restore purchases to re-apply it after reinstalling or switching devices. On web / browser-extension builds, the Merchant of Record's checkout gives you a redeemable key directly; paste it into Settings > Activate > Redeem key (keep it - that's also how you recover the license if you lose it or move devices).
Purchases are made through Google Play (Android) or a Merchant of Record for web / extension builds. Those parties are the seller of record for their channel and their terms also apply to the transaction.
3. Packs as dated editions
Some premium content may be offered as separately purchasable packs. A pack is a dated edition - a snapshot of data (for example, a tax table or a jurisdiction's rules) as of a stated date. A pack is not a subscription and does not guarantee future updates. Newer editions may be offered as separate purchases. Packs are cryptographically signed and sealed to your license; they are verified before use and will not open if tampered with or if the signature does not verify.
4. Availability of planned features
Some features described in marketing or documentation (for example, the optional ConvertVecta signed-FX refresh, in-app purchasing, and premium catalog packs) may be planned but not yet available in a given release. We do not guarantee that any planned feature will ship or ship by any date. Your rights are governed by the Apps as actually delivered to you.
5. No professional advice; informational only
The Apps are calculation and reference tools only. Outputs are informational and are not professional advice. In particular, and without limitation:
- FinanceVecta output is not financial, investment, accounting, or tax advice.
- ConstructionVecta code checks (e.g., IRC / ADA references) are reference aids only and are not a substitute for a licensed engineer or the Authority Having Jurisdiction (AHJ).
- ManufacturingVecta speeds/feeds and machining outputs are planning aids and must be verified before cutting.
- ElectronicsVecta output is a reference aid and must be independently verified for any safety-relevant use.
You are solely responsible for verifying results before relying on them.
6. No warranty
The Apps are provided "as is" and "as available," without warranty of any kind, express or implied, including without limitation warranties of merchantability, fitness for a particular purpose, accuracy, and non-infringement. We do not warrant that the Apps will be error-free or that any calculation is accurate or fit for your purpose.
7. Limitation of liability
To the maximum extent permitted by law, we will not be liable for any indirect, incidental, special, consequential, or punitive damages, or for any loss of profits, data, goodwill, property damage, or personal injury arising from or related to your use of the Apps or reliance on their output. Our total aggregate liability for any claim relating to the Apps will not exceed the amount you paid us for the App in the twelve months before the claim (which, for free users, is zero). Some jurisdictions do not allow certain limitations; those limits apply only to the extent permitted.
8. Refunds
Refunds are handled under the policy of the purchase channel and our Support & Refund Policy. For Google Play purchases, request through Google within 48 hours; after 48 hours contact support@corevecta.com. CoreVecta offers a full refund through 14 calendar days for a first purchase of the affected one-time SKU, subject to the policy, fraud/abuse checks, and applicable law. A refund or chargeback revokes only the exact refunded SKU.
9. Termination
This license terminates automatically if you breach these Terms. We may revoke a license that was refunded, charged back, or obtained fraudulently; a revoked license degrades to the free tier.
10. Governing law and disputes
These Terms are governed by the laws of the State of Wyoming, USA (CoreVecta LLC's state of registration), without regard to conflict-of-laws rules. The exclusive venue for disputes is the state and federal courts located in Wyoming, USA, unless mandatory local law provides otherwise.
11. Changes
We may update these Terms. Continued use after an update constitutes acceptance of the revised Terms. The effective date will be updated accordingly.
