Terms of Service and Sale
Terms of Service and Sale
Version 2.0 — published 28 August 2026, effective 28 September 2026. Until that date, version 1.0 continues to apply to existing contracts.
These Terms are drafted in French. The French version is the authoritative one; this English text is provided for information. In case of discrepancy, the French version prevails.
Preamble — who we are
Shortstop (the “App” or the “Service”) is published by:
Missyl, a French société par actions simplifiée with share capital of €100 Registered office: 35 avenue Jean Jaurès, 69780 Mions, France Company number (SIREN): 100 638 865 — Trade register: RCS Lyon 100 638 865 EU VAT number: FR33 100638865 President: Paul Tuet Contact: contact@missyl.fr
These terms and conditions (the “Terms”) govern your use of the App and any purchase made within it. They are available at any time from the App (Settings → Terms of Service) and from this site.
1. Scope and contractual documents
1.1 The Terms, together with the annexes below, form the entire agreement between you and Missyl:
- Annex 1 — Referral programme rules
- Annex 2 — Money-back guarantee
- Annex 3 — Lifetime upgrade offer
1.2 Each annex governs the programme it describes and prevails, for that programme, over the general provisions of the Terms.
1.3 The version applying to a purchase is the one in force on the day of that purchase. Every version is numbered and dated. For the referral programme (Annex 1), the version of the rules in force on the day you enrol is recorded at that time and is the version applied to you until your participation ends. For Annexes 2 and 3, the applicable version is the one in force on the day of your purchase, as published and dated here.
1.4 By using the App you acknowledge that you have read and accept the Terms. By making a purchase you expressly accept them.
2. Definitions
| Term | Meaning |
|---|---|
| Third-party platforms | The applications and services published by third parties on which Shortstop acts: YouTube, Instagram, TikTok, Snapchat, and any other application added later. |
| Plan | A paid offering: weekly, monthly, annual, or Lifetime Access. |
| Lifetime Access | The one-off payment offering, defined in section 7. |
| Google Play | Google’s app store, through which the App is distributed and all payments are processed. |

3. What Shortstop does — and what we cannot guarantee
This section matters. It describes a real, structural limitation of the Service. Please read it before purchasing.
3.1 Nature of the Service
Shortstop is software running on your Android device that uses the system accessibility API to detect and then interrupt the display of short-form video content inside Third-party platforms. Detection and blocking happen locally, on your device.
3.2 Shortstop depends on applications we neither publish nor control
Missyl is not affiliated with, partnered with, or endorsed by Google, Meta, ByteDance, Snap or any other publisher of the Third-party platforms, and has no agreement with them.
To identify content to block, Shortstop relies on the structure of those applications' interfaces. Those publishers change their interfaces freely, unilaterally and without notice, and may introduce measures that make detection impossible.
3.3 Best-efforts obligation
Missyl is therefore bound by a best-efforts obligation (obligation de moyens), not an obligation to achieve a specific result, as regards the effectiveness of blocking on any given Third-party platform at any given time.
By purchasing a Plan you expressly acknowledge that:
- an update to a Third-party platform may suspend or degrade blocking until we adapt the App;
- a Third-party platform may change such that blocking becomes lastingly, or even permanently, impossible;
- a Third-party platform may cease to exist, be renamed, or be removed from app stores;
- the set of covered Third-party platforms may therefore vary over time, up or down.
3.4 What we commit to
We commit, with the diligence of a professional publisher, to:
- monitor blocking on the covered Third-party platforms;
- publish, within a reasonable time, the fixes needed when a third-party change degrades the Service;
- publish that information on shortstop.app and in the App’s release notes when a Third-party platform ceases to be effectively covered, rather than leaving you to discover it.
3.5 Effect on your rights
The temporary or permanent unavailability of blocking on one or more Third-party platforms does not in itself constitute a lack of conformity of the Service, provided the Service remains functional on the other covered platforms.
If, however, the Service becomes lastingly inoperative across all Third-party platforms, section 14 (Discontinuation of the Service) applies.
Nothing in this section may deprive you of the statutory guarantee of conformity set out in section 12, or of any other right the law grants you as a consumer.
3.6 What Shortstop is not
- Shortstop is not a medical device and constitutes neither a diagnosis nor a treatment for any form of dependency. It is not a substitute for professional advice.
- Shortstop is not a parental control device within the meaning of applicable regulation and must not be presented as one.
- Shortstop is not a tamper-proof security device: a determined user can circumvent it (uninstalling, disabling the accessibility service, using a browser or another device).
3.7 Technical requirements and the role of Android
The Service requires a compatible Android device, Shortstop’s accessibility service to be enabled, and the granted permissions to be maintained. Android, or your manufacturer’s software layer, may disable the accessibility service on its own initiative (battery optimisation, app hibernation, memory management). The App warns you when it detects such a shutdown, but restoring the necessary permissions is your responsibility. Missyl cannot be held liable for a blocking failure resulting from a shutdown carried out by the operating system or by you.
4. Minimum age and no account
4.1 Age. The Service is intended for people aged fifteen (15) or over. If you are under 15, you may use the Service only with the agreement and under the supervision of your parent or guardian, who must have read these Terms. We do not ask for your age and have no way of verifying it; if you become aware that a minor is using the Service contrary to this clause, write to us at contact@missyl.fr.
4.2 No account. Using Shortstop does not require creating an account. Your preferences and usage history are stored on your device and linked to an Anonymous identifier. Data processing is described in the Privacy Policy.
4.3 As a result, we generally cannot identify you or retrieve your data from your name or email address. Keeping your Google Play receipt is therefore the only way to tie a purchase to you in the event of a claim.
5. Prices, payment and the role of Google Play
5.1 All purchases are made exclusively through Google Play. The price shown in the App is inclusive of all taxes, in the currency of your Google billing country.
5.2 Billing, accepted payment methods, collection of applicable VAT and issuance of receipts are handled by Google under its own terms. Depending on your territory, Google acts either as reseller or as payment intermediary.
5.3 We can only refund what was paid through Google Play. Any refund we grant — under the law, under section 12, or under any programme in Annexes 1 to 3 — is processed through Google Play and returned to the original payment method. We have no other disbursement channel.
5.4 We may change our prices at any time. A price change never affects a purchase already made. For active subscriptions, any increase is notified to you by Google Play under its rules, and you may cancel before it takes effect.
5.5 We run price tests: at a given moment, two users may be shown different prices for the same Plan. The price binding on you is the one displayed on your purchase screen when you confirm.
6. Subscription plans
6.1 Automatic renewal. The weekly, monthly and annual plans are auto-renewing subscriptions. Unless you cancel before the renewal date, the subscription renews automatically for an identical term and Google Play charges your payment method.
Under article L. 215-1 of the French Consumer Code, you are informed of the renewal date and of the cancellation deadline by Google Play, which sends you a renewal notice before each renewal and keeps your subscription status permanently available. As there is no user account, we have no other channel through which to reach you. If you did not receive that notice and the renewal went through, write to us: we will refund the unused period.
6.2 Free trial. Where a free trial is offered, its duration is stated on the purchase screen before confirmation. When the trial ends the subscription begins and the first charge is taken, unless you cancelled before the end of the trial. A free trial may only be used once per Google account.
6.3 Cancellation. You may cancel at any time and without giving a reason, directly through Google Play: https://play.google.com/store/account/subscriptions, or from the App, which takes you there. Cancellation takes effect at the end of the period already paid for: you keep access until that date, with no further renewal. No cancellation fee applies.
6.4 We have no technical ability to cancel your subscription on your behalf: only the Google account holder can do so.
7. Lifetime Access
7.1 What “lifetime” means
Lifetime Access is a one-off payment offering, with no renewal, no subscription and no subsequent charge of any kind.
Contractual definition. “Lifetime” refers to the period during which Missyl operates the Service. It does not refer to the duration of your life, nor to a perpetual term, nor to any fixed term.
No minimum operating period is guaranteed. Section 14 describes what happens if the Service is discontinued.
7.2 What is included
- Access to all Premium features of the Service;
- the App updates we publish during the operating period, at no additional cost.
7.3 What is not guaranteed
- The feature set over time. Features may be added, changed or removed, subject to section 13.
- The list of covered Third-party platforms, for the reasons set out in section 3.
- A fixed operating period, for the reasons set out in section 14.
7.4 Scope of the purchase
Lifetime Access is tied to the Google account that made the purchase. It is personal, non-transferable and non-resalable. It can be restored on a new device with the same Google account.
7.5 Associated commercial guarantee
Purchasing Lifetime Access at full price gives rise to the money-back guarantee described in Annex 2, on the conditions and within the limits set out there.
8. Money-back guarantee
Where offered, this guarantee lets you obtain a full refund of a Lifetime Access purchase, on request from within the App, for the period stated on the purchase screen.
It may be exercised once per person, and only where that Lifetime Access purchase is your very first paid purchase on Shortstop (section 4.2 of Annex 2). It immediately ends your access.
The full rules are in Annex 2. This commercial guarantee is in addition to, and does not replace, your statutory guarantees (sections 11 and 12 below).
9. Referral programme
Where offered, the referral programme lets a paying user obtain a refund of their own most recent payment once a set number of people they referred take out an eligible Plan themselves.
The full rules — eligibility, qualifying plans, number of referred friends required, timing, cancellation cases and anti-fraud measures — are in Annex 1.
10. Lifetime upgrade offer
Where offered, this lets a paying subscriber acquire Lifetime Access at a discounted price, with an automatic refund of their most recent subscription instalment.
The full rules are in Annex 3. This offer does not give rise to the guarantee in Annex 2.
11. Right of withdrawal
11.1 Principle. As a consumer you are in principle entitled to a fourteen (14) day withdrawal period for a distance contract (article L. 221-18 of the French Consumer Code).
11.2 Exception for digital content. The Service is digital content supplied immediately. By confirming your purchase, you expressly request that performance begin immediately and you expressly waive your right of withdrawal, in accordance with article L. 221-28, 13° of the French Consumer Code. This waiver is set out in these Terms, to which the purchase screen provides a permanent link, and you accept them expressly by confirming your purchase.
11.3 What we grant regardless. We have chosen not to stop at that exception:
- Lifetime Access at full price carries the commercial guarantee in Annex 2 where it is your first paid purchase;
- subscriptions are, in most cases, preceded by a free trial cancellable at no cost;
- you may write to us at contact@missyl.fr at any time: we review every refund request, and we regularly grant refunds beyond what the law requires.
11.4 Google Play separately applies its own refund policy, over which we have no control. You may approach Google directly.
12. Statutory guarantee of conformity
The Service is supplied to you in conformity with the contract. You benefit from the statutory guarantee of conformity for digital content and services under articles L. 224-25-12 et seq. of the French Consumer Code.
- For a one-off supply (Lifetime Access): the guarantee applies for two years from supply.
- For continuous supply (subscriptions): the guarantee applies throughout the supply period.
Where the Service is not in conformity, you may require that it be brought into conformity; if that is impossible, takes an unreasonable time or causes you major inconvenience, you may obtain a price reduction or termination of the contract, on the conditions set by law.
No provision of these Terms — in particular sections 3, 7 and 16 — may deprive you of this guarantee or narrow its scope. Any clause having that effect is deemed unwritten.
To invoke it: contact@missyl.fr.
13. Changes to the Service and to the Terms
13.1 Changes to the Service. We develop the App continuously. We may add, change or remove features, in particular for technical or security reasons or to adapt to Third-party platforms.
If a change degrades access to or use of the Service other than marginally, and is not imposed on us by an external constraint, we will inform you within a reasonable time and you may then cancel your subscription at no cost, or seek a proportionate remedy if you hold Lifetime Access.
13.2 Changes to the Terms. We may amend these Terms. Any substantial change is published on shortstop.app, and flagged in the App’s release notes, at least thirty (30) days before it takes effect. If you do not accept it, you may cancel your subscription at no cost before that date.
13.3 A change to the Terms never applies retroactively to a purchase already made or to a right already acquired under Annexes 1 to 3.
14. Suspension and discontinuation of the Service
This section describes what happens if Shortstop stops working or stops being operated. We prefer to state it plainly rather than leave the question open.
14.1 Possible causes
The Service may be suspended or permanently discontinued, in particular in the event of:
- a decision by Missyl to cease operating it;
- Missyl ceasing trading, being wound up or dissolved;
- removal of the App from app stores by their operator, or a change in their rules making distribution impossible;
- lasting technical impossibility, including as a result of changes to Third-party platforms (section 3);
- a decision by a public authority or a court;
- force majeure within the meaning of article 1218 of the French Civil Code.
14.2 Notice
Where discontinuation results from our own decision, we undertake to inform you in the App and by any other means available to us, giving at least three (3) months’ notice.
Where discontinuation results from an external cause (removal by the store, a third party’s decision, force majeure, forced cessation of trading), such notice may be impossible. We will then inform you as soon as we can.
14.3 Blocking continues on your device
Blocking runs locally. If our servers are shut down, the App already installed on your device will in principle keep blocking. We undertake, so far as we are able and if circumstances permit, to publish before shutdown a final version of the App that works without our servers, so that blocking outlives the Service.
If the App is removed from the Play Store, existing installations are not deleted from your device and continue to work. We control neither that decision nor its timing.
14.4 Effect on active subscriptions
We stop billing. The portion of the period already paid for and not yet elapsed is refunded to you, pro rata, through Google Play. That refund is issued manually from our Google Play console: if you have not received it within thirty (30) days, write to us at contact@missyl.fr with your order reference.
14.5 Effect on Lifetime Access
Since Lifetime Access is granted for the period during which the Service is operated (section 7.1), its discontinuation does not, in itself, give rise to a refund.
However, where discontinuation occurs so soon as to deprive your purchase of its economic consideration, Missyl will offer you a proportionate remedy: a full or partial refund, or transfer to an equivalent offering. That assessment takes into account the price paid, the time elapsed since purchase, and the cause of discontinuation.
Your rights under the statutory guarantee of conformity (section 12) remain in all cases.
14.6 Programmes in Annexes 1 to 3
If the Service is discontinued, rights already acquired and not yet honoured under the programmes in Annexes 1 to 3 will be honoured, so far as Google Play still technically permits execution.
15. Use of the Service and termination by us
15.1 You undertake not to: circumvent the Service’s technical limitations or purchase controls; use the Service for fraudulent purposes; create artificial identifiers or purchases in order to benefit improperly from a programme in Annexes 1 to 3; resell, rent or share paid access; or decompile the App beyond what the law permits.
15.2 In the event of an established breach of section 15.1, we may suspend your access to the programmes in Annexes 1 to 3, cancel an improperly obtained benefit and, where appropriate, end your access. Any such decision is notified to you with reasons, and you may challenge it at contact@missyl.fr.
15.3 Save in the case of established fraud on your part, termination on our initiative gives rise to a refund of the paid but unelapsed portion of the period.
16. Liability
16.1 Missyl is bound by a best-efforts obligation in supplying the Service, as set out in section 3.
16.2 Missyl is not liable for:
- content distributed by Third-party platforms, their terms of use, or their changes;
- Google’s decisions, in particular regarding distribution, billing, refunds or removal of the App;
- a blocking failure resulting from the accessibility service being disabled by the operating system, a manufacturer software layer, or you (section 3.7);
- the use you make of the Service, or decisions you take on the basis of the statistics it displays.
16.3 Cap. To the extent permitted by law, Missyl’s liability under these Terms is capped at the sums you have actually paid it for the Service.
16.4 Carve-outs. The cap in section 16.3 does not apply in cases of wilful misconduct, gross negligence, personal injury, or where the law prohibits such a limitation. It does not affect the statutory guarantee of conformity (section 12).
17. Intellectual property
17.1 The App, its code, interfaces, texts and graphic elements are the exclusive property of Missyl. The Shortstop trademark and logo belong to Missyl.
17.2 We grant you a personal, non-exclusive, non-transferable and revocable right to use the App for the duration of your access.
17.3 Third-party trademarks. YouTube, Instagram, TikTok, Snapchat and the other names mentioned are the trademarks of their respective owners. They are used descriptively only, to identify the applications on which Shortstop acts. Missyl is not affiliated with, endorsed by, or sponsored by those owners.
18. Personal data
Processing of your data is described in the Privacy Policy, which forms an integral part of these Terms. You have rights of access, rectification, erasure, restriction, portability and objection, exercisable at contact@missyl.fr, and the right to lodge a complaint with the French data protection authority, CNIL.
19. Advertising
Free use of the Service may involve the display of advertising, including rewarded video ads. Paid Plans are ad-free. Advertising partners and related processing are described in the Privacy Policy.
20. Complaints, mediation and disputes
20.1 Contact us first. Any complaint should be sent to contact@missyl.fr. We undertake to reply within fifteen (15) working days.
20.2 Consumer mediation. Under article L. 612-1 of the French Consumer Code, you are entitled to free recourse to a consumer mediator to settle a dispute amicably, after first attempting to resolve it directly with us.
The appointment of our mediator is in progress. Until it is completed, please write to us at contact@missyl.fr: we undertake to reply within the time set out in section 20.1 and to seek an amicable solution. The mediator’s details will be published here as soon as the appointment is made, and you will be able to refer any dispute to them, including one arising before that date. This does not deprive you of any of your rights, in particular those in sections 20.3 and 20.5.
20.3 Consumers resident in the European Union. You may also contact the European Consumer Centre in your country of residence. (The EU Online Dispute Resolution platform ceased operating on 20 July 2025 and is therefore no longer referenced here.)
20.4 Governing law. These Terms are governed by French law.
20.5 Jurisdiction. If you are a consumer, you retain the benefit of the mandatory provisions of the law of your country of residence and may bring proceedings either before the French courts or before those of your place of residence. No provision of these Terms requires you to waive access to the courts, to submit to arbitration, or to waive any collective action.
21. Miscellaneous
21.1 Severability. If any provision is held void or unwritten, the remainder continues to apply.
21.2 No waiver. Failure to rely on a provision does not waive the right to rely on it later.
21.3 Language. These Terms are drafted in French. The French version prevails. Translations are provided for information.
21.4 Assignment. Missyl may assign this contract as part of a corporate transaction or a sale of its business, without affecting your rights. You will be informed.
