Terms of Service — Sementeira

Effective date: 2026-05-21

These Terms govern your use of Sementeira (the "App"), published by Kebrabsoluta Unipessoal Lda ("we", "us"), a Portuguese sole-shareholder limited company. By installing or using the App you accept these Terms. If you do not accept them, do not use the App.

1. What the App does

Sementeira is a mobile gardening companion. It tracks plants, plans companion planting, diagnoses pests and diseases, integrates with Bluetooth soil sensors, and lets users post local-produce listings in a peer-to-peer marketplace.

2. Eligibility

You must be at least 16 years old to use the App. By using it you confirm you meet this requirement.

3. Your data, your device

Your gardening data (plants, zones, tasks, diagnoses, listings, sensor readings, settings) is stored on your device only. We do not back it up. You are responsible for backups. If you uninstall the App, factory-reset your device, or lose your phone, that data is lost.

4. AI diagnosis and biological-only recommendations — IMPORTANT DISCLAIMER

The disease-diagnosis feature, including the on-device model and the Claude Haiku-powered backend, is advisory only. Plant disease identification from photos is inherently uncertain. Visual symptoms overlap between conditions. The model has a stated training accuracy but no guarantee of correctness on your plant in your conditions.

All treatment suggestions are restricted to biological and organic methods. We do not recommend synthetic pesticides. However:

• We do not warrant that any suggested treatment will cure or improve your plant.
• You decide what to apply to your plants. Always read the label of any substance (even organic ones) and consider local agricultural extension advice, especially for edible crops.
• We are not liable for crop damage, yield loss, allergic reactions, or other consequences of acting on the App's suggestions. Use your own judgment.

5. Bluetooth sensors

The App reads from third-party Bluetooth soil sensors (e.g. Mi Flora). We do not manufacture, certify, warrant, or support these devices. Calibration, accuracy, and battery life are the responsibility of the device manufacturer.

6. Marketplace

The marketplace is a peer-to-peer discovery feature. Listings are created and stored locally. No in-app payments. No transaction processing. No buyer or seller verification.

• We are not party to any transaction between users.
• We do not guarantee that listed goods exist, are of merchantable quality, are accurately described, or are legally sold.
• You are responsible for complying with all applicable laws when selling or buying produce (food safety, VAT, agricultural regulations).
• Direct sales of fresh produce by individual small producers are typically exempt from VAT in Portugal up to certain thresholds — check your own situation with a tax adviser; we provide no tax advice.

7. Acceptable use

You may not:

• Reverse-engineer, decompile, or attempt to extract the App's source code (this clause is permissive only to the extent allowed by EU Directive 2009/24/EC).
• Use the App to harass, defame, or post unlawful content in marketplace listings.
• Bypass App permissions or attempt to access another user's device data through paired sensors.
• Use the diagnosis API for non-personal commercial throughput without prior agreement.

8. Intellectual property

The App, its source code, its design, the trained TFLite model, and the "Sementeira" name are owned by us or our licensors. PlantVillage training images are CC BY-SA 4.0 (© Mohanty, Hughes & Salathé, 2016). The App is licensed to you for personal, non-exclusive, non-transferable use.

Your gardening data is yours. We claim no rights over plant records you enter or photos you take.

9. Warranty disclaimer

The App is provided "as is" and "as available". To the maximum extent permitted by law, we disclaim all warranties (express or implied), including merchantability, fitness for a particular purpose, accuracy of disease identification, and non-infringement.

Nothing in these Terms limits or excludes liability that cannot be limited or excluded under applicable Portuguese law (notably for fraud, gross negligence, or death/personal injury caused by our negligence).

10. Limitation of liability

To the maximum extent permitted by law, our total aggregate liability arising out of or relating to the App in any twelve-month period is limited to €50 or the total fees you paid for the App in that period (whichever is greater). The App is currently free; any future paid tiers will state a separate liability cap if higher.

We are not liable for: lost profit, lost data, crop damage, lost goodwill, business interruption, or any indirect, incidental, special, or consequential damages.

11. Changes to the App and Terms

We may modify the App and these Terms. Material changes to the Terms will be announced in-App on next launch and the "Effective date" above will be updated. Continued use after a change constitutes acceptance.

12. Termination

You may stop using the App at any time by uninstalling it. We may suspend or terminate access to the diagnosis backend if you abuse it (e.g. automated requests, prompt-injection attempts, illegal content).

13. Governing law and jurisdiction

These Terms are governed by Portuguese law, excluding its conflict-of-laws rules. Any dispute will be brought before the competent courts of Lisbon, Portugal, without prejudice to your mandatory consumer-protection rights in your country of residence.

You may also use the EU Online Dispute Resolution platform at https://ec.europa.eu/consumers/odr.
