Effective as of March 5, 2026.
These Terms of Sale govern the sale of subscriptions to the Effect.Labs service, a premium CSS and JavaScript effects library accessible online.
Effect.Labs offers limited free access and premium access through a subscription. The premium subscription price is determined by a community-based degressive pricing system: as the number of active subscribers grows, the price decreases for all members, including existing subscribers.
| Plan | Access |
|---|---|
| Free | ~70 effects marked "FREE" |
| Premium (monthly or yearly) | 664+ effects (all), updates included |
The monthly price (excl. VAT) for the premium subscription changes according to the following tiers:
| Tier | Number of subscribers | Monthly (excl. VAT) | Yearly (excl. VAT) |
|---|---|---|---|
| Early Bird | 0 - 499 | ||
| Standard | 500 - 999 | €14.90 | €149 |
| Community | 1,000 - 4,999 | €7.90 | €79 |
| Massive | 5,000+ | €4.90 | €49 |
Applicable rules:
Prices are displayed excluding taxes (excl. VAT) in euros (€). The applicable VAT depends on the buyer's country of residence, in accordance with the rules in force for digital services:
In accordance with European regulations, the VAT of the destination country (OSS regime) applies once B2C intra-EU sales exceed €10,000 in the calendar year. Below this threshold, French VAT (20%) applies to all B2C EU sales.
The total amount including taxes is calculated and displayed before payment validation. All transactions are billed in euros (€). Any currency conversion fees are the responsibility of the buyer and depend on their banking institution.
The transition to the "Standard" tier (from 500 subscribers) results in a price increase from €9.90 to €14.90/month (excl. VAT) for new subscribers. Existing subscribers will be informed by email at least 30 days before any price change linked to a tier change. In case of disagreement, the subscriber may cancel their subscription free of charge before the new price takes effect.
The number of subscribers and the current tier are displayed in real time on the website homepage.
Subscribing to the premium plan follows these steps:
Payment is made by credit card through the secure Stripe platform (PCI DSS Level 1 certified). No card data is stored on our servers.
The subscription becomes active as soon as payment is confirmed by Stripe. A confirmation email is sent to the address associated with your account.
Subscriptions are automatically renewed at each billing period unless cancelled beforehand.
In accordance with Article L221-28, 13° of the French Consumer Code (Code de la consommation), the right of withdrawal cannot be exercised for digital content provided immediately after purchase.
Upon subscribing, you expressly acknowledge and agree that:
This dual consent is collected through two separate checkboxes before payment validation.
OptiMetier retains all intellectual property rights over the effects, source code, design and content of the Effect.Labs service. The subscription grants a non-exclusive, non-transferable, personal license to use the effects:
Free effects remain accessible without a subscription and without time limitation.
After cancellation: premium effects already integrated into your projects deployed before the cancellation date remain usable. However, you may no longer access the premium library, download new effects, or benefit from updates released after cancellation.
The subscription is taken out for the chosen duration (monthly or yearly) and renews automatically.
In accordance with Articles L215-1 to L215-3 of the French Consumer Code, we will inform you by email, no earlier than three months and no later than one month before the renewal date of your subscription, of your right not to renew. If you do not receive this information, you may cancel the contract at any time from the renewal date, without penalty, and obtain a pro-rata refund of the remaining period, within 30 days.
In accordance with French Decree No. 2023-417 of May 30, 2023, you may cancel your subscription directly online from your account dashboard, by following the cancellation steps accessible from the Stripe management portal. Online cancellation is free.
You may also cancel by contacting effects-lab@optimetier.fr. Cancellation takes effect at the end of the current paid period — no pro-rata refund is due (except as provided in Article L215-1 above).
Effect.Labs undertakes to provide the service with due care and in accordance with industry standards, this being an obligation of means (best efforts).
We are committed to maintaining service availability but do not guarantee:
In accordance with Articles L224-25-12 to L224-25-26 of the French Consumer Code, consumers benefit from a legal guarantee of conformity for digital content and services. This guarantee applies for a period of two years from the provision of the digital content.
In the event of a conformity defect found during this period, the consumer is entitled to have the digital content brought into conformity free of charge, within a reasonable time and without major inconvenience. Failing conformity, the consumer may obtain a price reduction or contract termination, under the conditions set out in Articles L224-25-20 et seq. of the French Consumer Code.
The consumer is exempt from proving the defect of conformity during the first 12 months following provision of the digital content.
For consumers: you benefit from the legal guarantee of conformity above and the mandatory provisions of consumer protection law. Nothing in these Terms of Sale shall limit or exclude the seller's legal liability for breach of its essential obligations.
For business customers (B2B): our liability is limited to the total amount paid by the customer under the subscription during the twelve (12) months preceding the damaging event. In no event shall Effect.Labs be liable for indirect, incidental, special or consequential damages.
The processing of your data is described in our privacy policy.
In case of a complaint, please contact us first at effects-lab@optimetier.fr. We commit to responding within 30 days.
If the dispute is not resolved amicably, you may use the consumer mediator free of charge (as provided by Articles L611-1 et seq. of the French Consumer Code):
These Terms of Sale are governed by French law.
Business buyers: in the event of a dispute, and after attempts at amicable resolution and mediation, the French courts within the jurisdiction of the seller's registered office (Alençon) shall have sole competence.
Consumers residing in the EU: in accordance with Regulation (EU) No 1215/2012, you may bring proceedings before the courts of your country of residence. You additionally benefit from the mandatory provisions of the law of your country of residence that cannot be waived by contract.
Consumers residing in the United Kingdom: you benefit from the protections of the Consumer Rights Act 2015 and the Consumer Contracts (Information, Cancellation and Additional Charges) Regulations 2013. You may bring proceedings before the competent English courts. These Terms of Sale do not deprive UK consumers of the rights granted by UK legislation.
Buyers outside the EU and the United Kingdom: any dispute shall be subject to the exclusive jurisdiction of the French courts, unless mandatory provisions of the buyer's local legislation require otherwise. Nothing in these Terms of Sale deprives a consumer of the rights granted by the legislation of their country of residence.
These Terms of Sale are originally written in French. An English translation is provided for informational purposes. In case of any discrepancy between the French and English versions, the French version shall prevail.
The Effect.Labs service is available in all countries where the Stripe payment platform operates. Access to the service may be restricted in countries subject to international sanctions (European Union, United States, United Nations). It is the buyer's responsibility to ensure that the use of the service complies with the legislation of their country of residence.
If any provision of these Terms of Sale is found to be null or unenforceable by a competent court, the remaining provisions shall remain in full force and effect.
