11. Contact Information

If you have any questions about these Terms of Service, please contact us at: support@plantdiagrams.com

12. Subscriptions and Billing

Plantdiagrams offers paid subscriptions in addition to a free tier. By starting a subscription, you authorize us and our payment processor to charge you the recurring subscription fee (monthly or yearly, as selected) and applicable taxes until you cancel. Subscriptions renew automatically at the end of each billing period unless canceled beforehand.

  • Pricing, features, and promotions are listed on the Pricing page.
  • Your billing period and renewal date are shown in your account or payment receipts.
  • Upgrades take effect immediately and may be charged prorated; downgrades apply at the next renewal.
  • We may update prices; material changes are communicated in advance and apply on renewal.

13. Cancellation

You can cancel your subscription at any time from your account. After cancellation, your plan remains active until the end of the current paid period, after which your account will revert to the free tier. Canceling prevents future charges but does not retroactively refund past charges unless expressly stated below.

14. Refunds

We aim to be fair and transparent. Refund requests are handled case-by-case, guided by the following principles:

  • Monthly/Yearly Subscriptions: Fees are generally non-refundable once a billing period begins. If you experienced service issues caused by us, contact support@plantdiagrams.com within 14 days and we may offer a prorated or full refund at our discretion.
  • EU Consumers – Right of Withdrawal: If applicable by law, you may have a 14-day cooling-off period. You acknowledge that access to digital services may begin immediately and you may lose this right once full delivery begins. We will honor applicable law.
  • Chargebacks: Please contact us first to resolve billing issues. Unwarranted chargebacks may lead to account suspension.

15. Lifetime Plan

We may offer a one-time, "lifetime" plan. "Lifetime" refers to the lifetime of the Product or service offering, not an individual’s lifetime. We reserve the right to modify non-core features over time, migrate infrastructure, and maintain reasonable fair-use limits. If the Product is discontinued, we will use reasonable efforts to provide continued access for a commercially reasonable period or an alternative of comparable value.

  • Lifetime purchases are non-recurring and generally non-refundable after 14 days, subject to applicable law.
  • Abuse, resale, or sharing outside permitted scope may result in suspension without refund.

We process personal data based on consent, contract necessity, and legitimate interests, as applicable.

  • Your Rights: You may request access, rectification, erasure, restriction, objection, and data portability to the extent provided by law.
  • Data Retention: We retain personal data only as long as necessary for the purposes described in our Privacy Policy or as required by law.
  • Subprocessors & Transfers: We may use reputable subprocessors and transfer data internationally with appropriate safeguards (e.g., SCCs). Details are available on request.
  • Security & Breach: We implement appropriate technical and organizational measures. If legally required, we will notify you and authorities of a data breach.
