Terms and Conditions

Last updated: September 2026

1. Identification and scope

The PlantDiary service (hereinafter "PlantDiary", "we") is provided by David Santos, tax number 209463171, a sole trader established in Portugal, operating the service under the PlantDiary brand. Contact: contact@plantdiary.app. These terms govern the use of the PlantDiary website, web app and mobile app. By creating an account or using the service, you declare that you have read and accept these terms and the Privacy Policy.

2. Purpose of the service

PlantDiary is a platform that helps you manage houseplants. It lets you record plants, houses and rooms, set watering and treatment schedules, store photos and notes, browse the species catalogue (Plantedex), unlock badges, receive email alerts and mobile notifications, get frost warnings based on weather data, and use artificial intelligence features to identify plants and suggest diagnoses (see clause 7).

3. Account and eligibility

  • Registration requires a valid email address, or signing in with Google or Apple.
  • You must be at least 16 years old to create an account.
  • The data you provide must be true and kept up to date.
  • You are responsible for keeping your credentials confidential and for all activity on your account. Tell us immediately if you suspect unauthorised use.
  • Each account is for personal, non-commercial use, unless otherwise agreed in writing.

4. Plans, prices and trial period

  • The available plans, their contents and prices are those shown on the pricing page at the time of subscription. Prices are stated in euros and include applicable taxes, unless stated otherwise.
  • Where a free trial period exists, its duration is stated before you subscribe. At the end of that period, and unless you cancel beforehand, the subscription converts to a paid one and is charged automatically.
  • Subscriptions renew automatically at the end of each period (monthly or annual) until you cancel them.
  • We may change prices and the composition of plans. Any change unfavourable to you is notified at least 30 days in advance and only applies from the following renewal period; if you disagree, you can cancel before it takes effect.
  • Non-payment may lead to suspension of access to paid features, after notice.

5. Payments

Payments are processed by Stripe. We neither receive nor store your card details. By subscribing, you also accept Stripe's applicable terms as the payment service provider. Managing your subscription and payment method is done through the billing portal available in your account.

If you subscribe through the mobile app (iOS or Android), payment is processed by the App Store (Apple) or Google Play, depending on your device — not by Stripe. In that case, the payment terms of those stores apply, and managing your subscription (including cancellation) is done in your Apple ID or Google account settings, not in our billing portal.

6. Right of withdrawal, cancellation and refunds

  • As a consumer, you have the right to withdraw from the contract within 14 days of subscribing, without giving any reason, under Portuguese Decree-Law 24/2014 and the EU Consumer Rights Directive. Simply let us know at contact@plantdiary.app.
  • By subscribing, you request that provision of the service begins immediately. If you withdraw after the service has begun, an amount proportionate to the period already used may be due.
  • You can cancel your subscription at any time through the billing portal.
  • After cancellation, you keep access until the end of the period already paid for.
  • Other than in the situations provided for by law, no pro-rata refunds are due for paid but unused periods.
  • If you subscribed through the App Store or Google Play, cancellations and refund requests are made directly with Apple or Google, following their own policies — not through our billing portal.

7. Artificial intelligence features and the informational nature of the service

Plant identification by photo, Plant Doctor, care suggestions, watering alerts and frost warnings are purely informational and indicative. They are generated automatically, using artificial intelligence models and third-party weather data.

  • Results may be incorrect, incomplete or out of date and are no substitute for assessment by a professional (agronomist, gardener, plant pathologist or vet).
  • We do not guarantee correct identification of species, nor correct diagnosis of diseases, pests or deficiencies.
  • Before applying any product, treatment, fertiliser or pesticide, you should read the label and follow the manufacturer's instructions and applicable law.
  • Some plants are toxic to people and animals. The information shown is no substitute for confirmation from specialist sources nor, in case of ingestion or contact, for immediately contacting a poison control centre or a vet.
  • Decisions you make based on these suggestions are your sole responsibility. PlantDiary is not liable for damage to plants, property, people or animals resulting from following them.
  • AI features are subject to usage limits per period, as stated in the plan you subscribe to, and may be temporarily unavailable for technical reasons or because they depend on external providers.

8. User content

  • The content you enter (plants, photos, notes, records) remains yours. We claim no ownership over it.
  • You grant us a limited, non-exclusive, worldwide, royalty-free licence to store, reproduce and process that content only to the extent necessary to provide you with the service — which includes sending it to the providers identified in the Privacy Policy, such as the AI provider, when you use those features. This licence ends when you delete the content or your account.
  • You warrant that you hold the necessary rights over what you upload and that you do not infringe third-party rights, in particular copyright and image rights.
  • We do not use your content for advertising, nor do we make it public, except if and when you share it yourself through the sharing features.
  • You are responsible for keeping copies of content you consider important. The service is not a substitute for a backup system.

9. Acceptable use

It is prohibited to use the service to:

  • Carry out illegal activities or activities that infringe third-party rights
  • Upload offensive, defamatory or malicious content, or content that infringes copyright
  • Upload content containing third parties' personal data without a basis for doing so
  • Reverse engineer, carry out automated scraping, or circumvent usage limits and quotas
  • Attempt to access accounts, data or systems that are not yours
  • Overload, disrupt or compromise the security and integrity of the service
  • Resell or make the service available to third parties without our written authorisation

10. Suspension and termination

  • You can delete your account at any time, in settings or through the account deletion page. Deletion follows the timescales set out in the Privacy Policy.
  • We may suspend or terminate access, in whole or in part, in the event of serious or repeated breach of these terms, fraudulent use, or risk to the security of the service or of third parties. Wherever possible, we give prior notice and an opportunity to remedy; in the event of suspension through no fault of yours, we refund the proportionate part already paid and unused.
  • If we discontinue the service entirely, we give at least 30 days' notice and provide means for you to export your data.

11. Service availability

We strive to keep the service continuously available, but we do not guarantee uninterrupted availability or freedom from errors. The service may be temporarily suspended for maintenance, updates, or for reasons beyond our control (provider or network failures, or force majeure), with prior notice wherever possible. Alerts and notifications depend on third-party services (email, push notifications) and on your device's configuration, so we cannot guarantee timely delivery — you should not rely on them exclusively.

12. Limitation of liability

To the maximum extent permitted by applicable law, PlantDiary is not liable for indirect damages, loss of profits, loss of data or loss of opportunity arising from the use of, or inability to use, the service. PlantDiary's total liability, for all events occurring within a 12-month period, shall not exceed the amount you have paid us in the 12 months preceding the event giving rise to the damage.

Nothing in these terms excludes or limits our liability for wilful misconduct, gross negligence, death or personal injury, nor the rights that consumer protection law grants you and which cannot be waived by agreement — including the rights in the event of lack of conformity of digital content or services under Portuguese Decree-Law 84/2021.

13. Intellectual property

All platform content (interface, code, species catalogue texts, brand and logo) is the property of PlantDiary or its licensors and is protected by intellectual property rights. You are granted a personal, limited, revocable and non-transferable right of use for as long as your account is active. Data entered by you belongs to you, under clause 8.

14. Changes to the terms

We may update these terms, in particular due to changes to the service or to the law. Significant changes are notified by email or in the app at least 30 days in advance. If you disagree, you can stop using the service and delete your account before the effective date; continuing to use it after that date means you accept the new version.

15. Consumer dispute resolution

In the event of a dispute, contact us first — we will seek to resolve it in good faith. As a consumer, you may turn to alternative consumer dispute resolution bodies, under Portuguese Law 144/2015, in particular CNIACC — the national consumer arbitration centre, or the arbitration centre for your area of residence. The full list is available at consumidor.gov.pt. If you reside in another EU country, you may also use the dispute resolution bodies available there.

16. Governing law and jurisdiction

These terms are governed by Portuguese law. If you are a consumer, you retain the right to bring proceedings before the courts of your domicile and you benefit from the mandatory provisions of your country of habitual residence in the European Union. In relations with users who are not consumers, the courts of the district of Lisbon have jurisdiction, with express waiver of any other.

17. Final provisions

If any clause of these terms is held invalid or unenforceable, the remainder stay in force. Not immediately requiring performance of an obligation does not amount to waiving the right to require it later. These terms, together with the Privacy Policy and the Cookie Policy, constitute the entire agreement between the parties regarding use of the service.
