This is an English translation of the approved French terms. The French text remains available as the source version. A customer may expressly choose this English contract before payment; mandatory protections in the customer’s country of habitual residence remain unaffected where applicable.

1. Purpose, definitions and formation of the contract

Plumelin is an online writing tool published by Flying Golem SAS, 1 Keroulard Vras, 29530 Plonévez-du-Faou, France. In particular, it allows users to write and structure a manuscript, build its fictional world, synchronise projects, collaborate, import, export and, on request, use certain assisted-analysis functions. Contact: hello@plumelin.com, +33 2 55 05 44 50. Full information appears in the legal notice.

In these terms, “Service” means Plumelin; “Customer” means the person who creates an account or subscribes to a plan; “Consumer” means a person acting for non-professional purposes; “Professional” means a person acting in the course of their professional activity; “Project” means the collection consisting of a manuscript, its structure, its fictional world and its metadata; “Workspace” means the environment in which an owner manages projects and collaborators; and “Subscription” means paid access for a monthly or annual period.

These terms become binding when they are brought to the Customer’s attention before account creation or ordering. By completing the acceptance mechanism presented, the Customer accepts them without reservation. For a paid subscription, final confirmation constitutes the order. Flying Golem records the version, language, date and evidence of acceptance, then sends a confirmation and a copy of the contract on a durable medium.

The order summary and any expressly accepted special condition prevail over these terms for their specific subject matter. For a Professional, the Data Processing Agreement prevails in the event of a conflict concerning processing carried out on its behalf. Stripe’s or Link’s terms govern payment operations provided through those services, without changing Flying Golem’s obligations relating to the product.

2. Access, account and technical operation

Only people who are at least 18 years old and legally capable of entering into a contract may create an account. The Customer provides a valid email address, protects access to that mailbox and reports any unauthorised use. Plumelin uses passwordless authentication through temporary codes or links; the Customer remains responsible for the devices and email accounts under their control.

Plumelin uses a local-first architecture with synchronisation. The manuscript, its structure, its fictional world and certain settings may be stored in the browser to support offline writing. With an account, projects are also synchronised with the server. Functions that depend on the server—including synchronisation between devices, invitations, collaboration and certain imports, exports or analyses—require a connection and may be unavailable offline.

The Customer uses a current browser, device and compatible connection. The Customer is responsible for maintaining their environment and regularly exporting important projects. Limitations specific to a browser, its local storage or a device are not a commitment concerning availability of the Service.

The project owner controls invitations and roles. A collaborator receives only the permissions associated with their role or profile. Anyone who creates an account or places an order for an organisation warrants that they are authorised to bind it and administer the relevant access.

3. Plans, prices and renewal

The current features and limits of each plan are presented on the Pricing section before ordering. The Free plan includes writing, structure, fictional-world tools, synchronisation, history and basic exports. Author additionally includes assisted imports up to the published limit, suggestion mode and advanced exports. Studio additionally includes open collaboration on projects owned by the Customer, roles, comments and notifications. Invited users do not need Studio to join a Studio project.

Author
€7 per month, or €59 charged once for one year, including all taxes for a Consumer in France
Studio
€15 per month, or €126 charged once for one year, including all taxes for a Consumer in France

All invoiced prices are those in force on the date the order or renewal is recorded, after deduction of any applicable discounts or rebates. The total amount, currency, taxes, billing frequency, effective date, and date or method for determining the next renewal are displayed before payment. For a Professional, the amount excluding tax, taxes and total due are shown in the payment flow or invoice according to their country and tax status.

Subscriptions run for one month or one year and renew automatically for the same period until cancelled. By ordering, the Customer authorises the merchant of record to charge the selected payment method at subscription and at each renewal, according to the frequency and amount disclosed before each charge.

For a Consumer’s annual subscription, Plumelin sends a dedicated renewal email forty-five days before the renewal date. It states the amount and date and includes a link allowing the Customer to decline renewal directly. Any price change is communicated before it applies and does not alter the price of a period already paid. Where required by law, the Customer may reject a material change and end renewal.

4. Ordering, payment and invoicing

Subscription payment and invoicing are handled by Stripe through Stripe Managed Payments. At payment, Sold through Link, LLC, or the entity identified in Checkout, acts as merchant of record for the transaction. Its name may appear on the payment page, invoice, receipts and bank statement. Flying Golem supplies Plumelin and remains responsible for access to the product, its conformity and functional support.

Before placing an order, the Customer can review the plan, billing frequency, total price and declared information, then correct any error. The final button states that the order entails an obligation to pay. The Subscription is activated after Stripe confirms payment. If a payment method fails or expires, the merchant of record may retry according to its rules; Flying Golem may suspend paid functions until the matter is resolved, after giving notice where possible.

The Customer can manage the Subscription in Plumelin or through the Link interface. Any cancellation, reactivation or change confirmed by Stripe is recorded and confirmed on a durable medium. The merchant of record supplies the invoices and tax documents relating to the transaction. The Professional supplies accurate billing information, including its registered business name, address and VAT number where it has a valid one.

For a request concerning payment, an invoice or a transaction refund, the Customer may use Link support. For product access, a defect or a request based on Plumelin’s conformity, the Customer contacts Flying Golem at hello@plumelin.com. Flying Golem and Stripe share the information necessary to handle the request within the limits described in the privacy notice.

5. Right of withdrawal and refunds

In principle, the Consumer has fourteen days to exercise the right of withdrawal without giving a reason. This period begins on the day the Consumer confirms the distance subscription and accepts the contract. The procedure and model form are available under Withdrawal.

Where performance begins before that period ends at the Consumer’s express request, Plumelin refunds the price paid after deducting the amount proportionate to the service actually supplied until the request is received. Merely using the Service does not amount to waiving this right.

Outside withdrawal, the statutory conformity guarantee and other mandatory rights, no additional automatic refund is promised. Flying Golem or Stripe may nevertheless grant a commercial gesture case by case. A Stripe decision concerning the transaction does not deprive the Consumer of statutory remedies against Flying Golem concerning the Service.

6. Content, collaboration and permitted use

The Customer retains their rights over manuscripts, files and data they create or import. The Customer grants Flying Golem only the non-exclusive permissions necessary, for the period required to provide the Service, to store and synchronise them, display them to authorised collaborators, transform or analyse them on request, export them and delete them according to the Customer’s instructions.

The owner administers the Project. According to the published features, an editor may change the manuscript and fictional world, while a reader or review profile has limited access to reading, comments or suggestions. The owner checks the identity and needs of invited people, revokes access that is no longer needed and obtains the authorisations necessary to share content. A transfer of ownership is an administrative operation distinct from literary attribution.

The Customer warrants that they hold the rights and legal bases needed for submitted content. The Customer must not use Plumelin to infringe another person’s rights, unlawfully process data, distribute prohibited content, bypass access controls, search for a vulnerability without authorisation, introduce malware, automate abusive use or disrupt the Service. Flying Golem may remove manifestly unlawful content or restrict access under the conditions in section 9.

7. Import, export, artificial intelligence and certification

Import and export

Imports and conversions depend on the quality and structure of the source file. The Customer checks the result before continuing their work. Exports are produced in the formats and profiles available when requested; Flying Golem does not guarantee compatibility with every application, printer or publishing workflow. Temporary export files retained on the server are deleted after twenty-four hours.

Assisted analysis

Artificial-intelligence analysis is optional and starts only through an express action. Basic import remains available without sending the manuscript to an artificial-intelligence provider. When assisted analysis is selected, only the necessary text windows are sent to the service identified in the privacy notice. Flying Golem does not use manuscripts to train a foundation model and selects a service whose terms prohibit that training from Plumelin prompts and responses. Suggestions may be inaccurate; the Customer checks them before retaining them.

Plumelin Certification

When offered, Plumelin Certification establishes technical evidence, fingerprints and receipts concerning a specific project or export. It is neither a legal deposit nor a decision about authorship of a work, and it does not guarantee against every dispute. The private manuscript and detailed evidence file do not become public. The title, pen name, contributors, publisher, ISBN or other presentation information is made public only through a separate choice by the holder and can be removed without falsifying the historical existence of the cryptographic evidence.

8. Availability, security and force majeure

Flying Golem uses reasonable means to support availability, security and correct operation of the Service. Maintenance, network incidents, security updates or provider outages may temporarily interrupt online functions. Local functions that are already loaded may remain available depending on the browser and device state.

No service level or availability rate is guaranteed unless a separate written commitment is agreed with a Professional. Flying Golem gives notice of significant planned maintenance where its nature permits and handles incidents according to their severity.

Neither party is liable for a delay or failure directly caused by an event reasonably beyond its control whose effects could not have been avoided by appropriate measures, including a widespread network outage, disaster, authority decision or exceptionally large-scale attack. The affected party informs the other and limits the effects as far as reasonably possible. Payment obligations already due and the Consumer’s mandatory rights remain applicable.

9. Cancellation, suspension and erasure

The Customer can stop renewal from the Withdrawal and cancellation page, the account’s billing settings or the Link interface. Unless a right allows it to end earlier, access to paid functions remains available until the end of the period already paid for, after which the account returns to the Free plan.

Before erasing an account, the Customer can download an archive of projects, settings and metadata present on the device and separately request account data retained on the server. Erasing an account associated with a Subscription cancels it immediately. No further charge is made and access to the remaining prepaid period ends with the account. Before confirmation, the application shows the plan and remaining prepaid days. Erasure does not waive a statutory right to a refund; where a withdrawal period remains open, Plumelin asks the Customer to exercise that right first.

Flying Golem may suspend all or part of access in the event of a security risk, fraud, non-payment, manifestly unlawful content or a serious breach of these terms. The measure is proportionate, limited to what is necessary and preceded by notice and an opportunity to remedy where the situation permits. A continuing or irremediable breach may lead to termination, without affecting the Consumer’s mandatory rights or reasonable access to their data where required by law.

10. Plumelin intellectual property

Flying Golem and its licensors retain their rights in Plumelin’s software, website, trademarks, models, documentation, interfaces and graphic elements. The contract grants the Customer a personal, non-exclusive right, non-transferable unless expressly authorised, to use the Service for the duration of their access and according to the selected plan.

This licence transfers no right in the Plumelin code or trademark and does not authorise their extraction, resale, provision as a competing service, technical circumvention or reverse engineering, except to the extent expressly permitted by law. Exported files incorporate the Customer’s content; their technical format gives Flying Golem no right in the Customer’s work.

11. Statutory guarantees and liability to consumers

Statutory guarantee of conformity for digital content and digital services

The consumer has two years from supply of the digital content or digital service to invoke the statutory conformity guarantee if a lack of conformity appears. During one year from the date of supply, the consumer need establish only the existence of the lack of conformity, not the date on which it appeared.

The statutory conformity guarantee entails an obligation to provide all updates necessary to maintain conformity of the digital content or digital service.

The statutory conformity guarantee entitles the consumer to have the digital content or digital service brought into conformity without undue delay following the request, free of charge and without major inconvenience.

The consumer may obtain a price reduction while keeping the digital content or digital service, or may terminate the contract and receive a full refund in exchange for giving up the digital content or digital service, if:

  1. The professional refuses to bring the digital content or digital service into conformity;
  2. Bringing the digital content or digital service into conformity is unduly delayed;
  3. Conformity cannot be restored without imposing costs on the consumer;
  4. Bringing the digital content or digital service into conformity causes major inconvenience to the consumer;
  5. The lack of conformity persists despite the professional’s unsuccessful attempt to restore conformity.

The consumer is also entitled to a price reduction or termination of the contract where the lack of conformity is so serious that it justifies an immediate price reduction or termination. The consumer need not first request that the digital content or digital service be brought into conformity.

Where the lack of conformity is minor, the consumer is entitled to cancel the contract only if the contract does not provide for payment of a price.

Any period during which the digital content or digital service is unavailable in order to restore conformity suspends the remaining guarantee period until the digital content or digital service is supplied in conformity again.

The rights above result from Articles L. 224-25-1 to L. 224-25-31 of the French Consumer Code.

A professional who, in bad faith, obstructs implementation of the statutory conformity guarantee is liable to a civil fine of up to €300,000, which may be increased to 10% of average annual turnover (Article L. 242-18-1 of the French Consumer Code).

In addition, the consumer benefits from the statutory guarantee against hidden defects under Articles 1641 to 1649 of the French Civil Code for two years from discovery of the defect. This guarantee gives the consumer the right to a price reduction if the digital content or digital service is retained, or a full refund in exchange for giving it up.

Flying Golem supplies the updates necessary for conformity and security for the duration of the Subscription or, for the Free plan, for as long as the relevant version of the Service continues to be offered. To invoke a statutory guarantee free of charge, the Consumer writes to hello@plumelin.com and describes the defect.

The limitations for Professionals in section 12 do not apply to Consumers. Flying Golem remains liable under generally applicable law, and nothing in these terms reduces guarantees, remedies or liabilities that cannot be limited by law.

12. Provisions specific to professionals

This section applies only to a Customer acting for purposes within their commercial, industrial, craft, professional or agricultural activity. A Professional whom the law sometimes gives consumer protection—including where the contract falls outside their main activity and the statutory conditions are met—retains that protection. Merely supplying a registered business name does not remove it.

Prices, VAT and payment

Professional prices are shown excluding tax where so indicated, then increased by applicable taxes; the Checkout summary and invoice state the total. The Professional supplies a registered business name, billing address and, where applicable, a valid intra-Community VAT number. The merchant of record applies an exemption or reverse charge where legally available and verified.

Subscriptions processed through Stripe Managed Payments are payable immediately using the selected method under the merchant of record’s terms. Any invoice issued directly by Flying Golem is payable by its due date or, where none is stated, within thirty days after performance of the service. Any delay results, without reminder, in interest at the rate applied by the European Central Bank to its most recent refinancing operation plus ten percentage points, without falling below three times the statutory interest rate, and a fixed €40 recovery-cost charge. Additional compensation may be requested with evidence where the costs incurred are higher.

Authority, administration and confidentiality

A person accepting the contract for the Professional warrants their authority to represent it. The Professional appoints and controls the administrators, project owners and collaborators in its organisation. Each party protects non-public confidential information received from the other, uses it only to perform the contract and discloses it only to people who need to know or where required by law. This obligation does not cover information that becomes public without fault, was already lawfully known or is lawfully obtained from a third party.

Service level and liability

No service level is guaranteed without a separate written agreement. Flying Golem is liable only for direct, foreseeable loss caused to the Professional by a proven breach. Except for gross negligence or wilful misconduct, personal injury, breach of an obligation that cannot be limited or any other exclusion prohibited by law, its total liability is capped at the amounts paid by the Professional during the twelve months preceding the event giving rise to the claim. To the extent permitted, this excludes indirect loss of profit, revenue, opportunity, reputation or data that could have been avoided through the exports reasonably expected.

Personal data

Where Flying Golem processes personal data contained in workspaces on the Professional’s behalf, the Data Processing Agreement forms part of the contract. The list of subprocessors and other recipients identifies providers, their role and location.

13. Personal data

Flying Golem collects and uses the personal data necessary to supply and secure the platform, manage accounts and subscriptions, answer requests, comply with its obligations and—only after a voluntary choice—measure or improve certain aspects of the Service. The purposes, legal bases, recipients, transfers, retention periods and rights are described in the privacy notice.

The privacy notice provides information about processing and is not a waiver of rights. Where consent is required for an optional function, it is requested separately and can be withdrawn as easily as it was given.

14. Changes to the terms

Flying Golem may change these terms to reflect legal, security, technical or functional developments. The date and version are shown at the start of the document. A material change applying to an existing contract is announced on a durable medium with reasonable notice. It does not retrospectively reduce a period already paid for.

Where applicable law so provides, or where a change goes beyond what is necessary for conformity of the Service, the Customer may reject the change and prevent renewal or end the contract according to their rights. The copy accepted with a paid order remains available in the account’s contract archive. Earlier versions may also be requested from hello@plumelin.com.

15. Complaints, mediation and applicable law

A complaint or support request may be sent to hello@plumelin.com. Flying Golem responds within a period reasonable for the nature of the request.

After first making a written complaint to Flying Golem that has not led to a satisfactory solution, the Consumer may refer the matter free of charge to the Centre de la Médiation de la Consommation de Conciliateurs de Justice (CM2C), 49 rue de Ponthieu, 75008 Paris, France. Online referral: www.cm2c.net/declarer-un-litige.php. Email: litiges@cm2c.net. Telephone: +33 1 89 47 00 14.

These terms are governed by French law. The Consumer retains the benefit of mandatory provisions in their country of habitual residence and may bring proceedings before the competent courts under the applicable rules. For a dispute between Professionals concerning formation, interpretation or performance of the contract, and after an attempt at amicable resolution, the Commercial Court of Quimper has express jurisdiction, including where there are multiple defendants or third-party proceedings, subject to any contrary mandatory rule.

If any provision is held invalid, the others remain applicable to the fullest extent permitted. Failure to exercise a right immediately does not waive that right.
