Terms
Subscription to the Ton Tandem software — trial, plans, cancellation.
In case of discrepancy, the French version prevails. French original
Last updated: 28 August 2026
These terms (hereinafter the “Terms”) govern access to the Ton Tandem software (tontandem.app) and the associated subscriptions.
The publisher is C.T. Conseil & Délégation, SAS with a share capital of 1 000 €, SIRET 101 099 794 00014, RCS Salon-de-Provence, 224 Allée Evariste Galois, 13880 Velaux (hereinafter “the Publisher”). Ton Tandem is the name under which the Publisher offers this service. VAT not applicable, article 293 B of the CGI (no VAT collected).
By creating an account and ticking the acceptance box, you accept these Terms. If you do not accept them, do not use the service.
1. Purpose
Ton Tandem is online business software for virtual assistants, OBMs and freelance Executive Assistants: following client missions and, depending on the formula, running their own business (prospecting and/or editorial).
There is no portal for the user’s end client. The subscription contract is exclusively between the Publisher and the user (or their company).
You may send a client a personalised link (file deposit in the vault, read-only mission follow-up). That link does not open a client account. You remain responsible for what you share in this way.
The functional detail of the formulas is described on tontandem.com/en/tarifs/. In case of discrepancy, these Terms and the Pricing page in force at the time of subscription prevail over any marketing material.
2. Account
Registration takes place on tontandem.app. You provide accurate information (identity, email) and keep your credentials confidential.
One account = one user. No multi-seat offering and no executive space in the current offer.
You are responsible for the data you enter in the tool, including information relating to your clients, and for the use you make of it.
3. Formulas
Three monthly formulas (VAT not applicable, art. 293 B of the CGI):
| Formula | Price / month | Contents |
|---|---|---|
| Missions | 19 € | Operational foundation (missions, client files, retainers, mission stats) |
| Visibility | 29 € | Foundation + one brick of your choice: prospecting or editorial (stats for that brick included) |
| Business | 39 € | Foundation + prospecting + editorial |
The amount charged is the amount stated (19 €, 29 € or 39 €). No VAT on top.
The brick chosen for Visibility is selected in the application, after registration.
4. Trial
Every new registration opens a 14-day trial from the creation of the account.
- A bank card is required at registration.
- No charge is made during the trial.
- The first payment is taken on the 15th day, unless cancellation is effective before that date.
- If you cancel during the trial, 0 € is charged.
The trial gives access to the entire software (foundation, prospecting and editorial). At registration, you indicate the formula you want after the trial. You may change it during the trial at no charge; the first debit will be for the formula active at the end of the trial.
5. Price, payment, invoices
Subscriptions are monthly, with no commitment beyond the current period.
Payment is due on the due date: automatic debit on the renewal date, via Stripe. The Publisher does not store card numbers. The bank statement wording may mention Stripe and/or TON TANDEM.
Invoices are issued by C.T. Conseil & Délégation and made available via the payment portal and/or the account area. They bear the mention VAT not applicable, article 293 B of the CGI.
If payment is not received on the due date, access may be suspended after notice. A “payment pending” status may appear in the application. The Publisher is not required to keep unlimited access in the event of non-payment.
In the event of late payment, late-payment penalties are due as of right, without reminder, at a rate equal to the interest rate applied by the European Central Bank to its most recent refinancing operation, plus 10 percentage points, together with a fixed indemnity for recovery costs of 40 € (articles L. 441-10 and D. 441-5 of the French Commercial Code).
6. Changing formula
- Upgrade (move to a higher formula, or add a brick): immediate. The price difference is billed pro rata for the current period.
- Downgrade (lower formula, or remove a brick): takes effect at the next renewal. The month started is due (a month started is a month finished).
Changes are made from the application (My account) or the payment portal.
7. Term, renewal, cancellation
The subscription renews tacitly each month, at the rate of the formula then active.
You may cancel at any time, from the payment portal or by writing to contact@tontandem.com.
- Cancellation during the trial: access until the end of the trial (or immediately if you so request); no charge.
- Cancellation after the trial: access remains open until the end of the period already paid; no refund of the current month.
The Publisher may cancel or suspend the account in the event of a serious breach of these Terms (fraudulent use, non-payment, harm to the service or to third parties), after notice where reasonably possible.
8. Right of withdrawal
The offer is addressed to professionals acting for their activity. The right of withdrawal provided for consumers does not apply to contracts concluded between professionals.
If, exceptionally, you contracted as a consumer: the digital service begins as soon as the account is opened, with your express agreement (box at registration). Pursuant to article L. 221-28 13° of the French Consumer Code, you then waive your right of withdrawal. The 14-day trial with no charge remains applicable.
9. Use of the service
You undertake to use the service in accordance with the law and these Terms: no intrusion, no abusive overload, no resale of the service, no unlawful content in the tool.
The Publisher endeavours to ensure reasonable availability. Interruptions (maintenance, incident, force majeure) may occur. They do not give rise to compensation, except in the event of a serious and proven breach by the Publisher.
Assistance suggestions (prioritising, help drafting an email, a procedure, a post or a follow-up) are aids. You remain solely responsible for what you validate, send or publish.
Ton Tandem prepares certain content (posts, prospecting messages); it does not send or publish them on your behalf, unless a function clearly indicated later.
Backups and security are organised according to the reasonable state of the art for a service of this size. A copy of your data (export) will be offered; until it is available in the app, a request to contact@tontandem.com is sufficient.
On account closure, access ends at the end of the period due. Operating data may be deleted after 30 days, except for a legal retention obligation (in particular invoices, 10 years).
10. Intellectual property
The software, the Ton Tandem mark, and the Publisher’s texts and visuals remain its property (or that of its rightholders). The subscription confers a personal, non-exclusive, non-transferable licence to use, for the duration of the subscription.
The content you enter (client files, texts, files) remains yours. You grant the Publisher the licence strictly necessary to host and display that content in the context of the service.
11. Liability
The tool assists your organisation; it does not replace your professional, accounting or legal obligations towards your clients.
The Publisher’s liability, if it were engaged, is limited to the amounts you have paid it in respect of the three (3) last months of subscription, excluding wilful misconduct or gross negligence, and excluding personal injury.
12. Personal data
The processing of registration, billing and usage data is described in the privacy policy.
For the data of your clients that you record in Ton Tandem, you are the controller; the Publisher acts as processor within the meaning of the GDPR, solely to provide the service.
13. Changes to the Terms and to prices
The Publisher may amend the Terms or the prices. Notice is given to you (email or mention in the app) before they take effect, with reasonable notice (at least 15 days for a price increase, except for a legal constraint).
Continuing the subscription after they take effect constitutes acceptance. If you disagree, you cancel before that date; the current month remains due.
A change of the Publisher’s legal entity (new company, same Ton Tandem name) will be notified. A new agreement and, where applicable, a new payment method may be required.
14. Governing law
These Terms are governed by French law.
In the event of a dispute, an amicable solution is sought first (write to contact@tontandem.com). Failing that, the competent courts of the Publisher’s registered office are seized, subject to mandatory rules of public policy.
