Preparing a Hylest capsule isn't
about dwelling on absence. It's about
making sure what truly matters
doesn't disappear with you.
Messages, memories, documents,
codes or wishes: some things
deserve to be found again
and passed on.
Messages, memories, documents, codes, or wishes: some things deserve to be found and passed on.
Passing on is also taking care of those who remain.
Protect what matters most in just four steps.
No technical knowledge required.
Create a capsule
Think of someone who matters. Create a capsule in their name in just a few clicks.
Add what you want to pass on
Insert your messages, videos, photos, documents, and personal codes: everything is centralized and protected in an encrypted space.
Link your capsule to its recipient
Associate the capsule with your loved one's Hylest account. It will be visible in their app, but its content will remain locked.
Hylest s'occupe du reste
Le moment venu, la capsule s'ouvrira automatiquement, ou manuellement grâce à une personne de confiance.
Secure, personal spaces
to preserve what matters most.
A capsule is a secure personal space dedicated to someone you choose.
Partner, children, family or friends…
Each capsule is personal, and only its designated recipient can access it through their own Hylest app.
Even after being linked to a recipient, your capsule remains fully editable at any time.
These are words we want to pass on,
and would never want to see disappear.
Sometimes, they are things
we are not yet ready to say,
but that we hope to entrust
when the time is right.

Nous répondons à vos questions.
Hylest est une application qui permet de transmettre automatiquement et en toute sécurité vos messages, documents, codes, souvenirs ou volontés à vos proches après votre décès, sous forme de capsules numériques personnelles.
Une capsule est un coffre-fort numérique destiné à une seule personne. Vous y placez ce que vous souhaitez transmettre : messages, photos, vidéos, documents, informations sensibles, volontés…
Elle reste invisible jusqu’au moment où elle doit s’ouvrir.
Every feature is designed to protect your data from the moment it is created.
Ender, l’oracle propriétaire dopé à l’IA, gère l’ouverture de manière lente et prudente.
Il envoie des vérifications espacées sur plusieurs semaines et ne considère une absence comme réelle qu’après un long processus — jamais rapidement.
L’ouverture respecte ensuite l’ordre que vous avez défini : semaine 1 conjoint/enfant, semaine 2 famille proche, etc.
Oui. Les capsules peuvent être modifiées à tout moment : photos, vidéos, messages, documents, absolument tout.
Le jour où votre capsule doit s’ouvrir, c’est la toute dernière version de votre coffre qui sera transmise à votre héritier.
L’accès à Hylest ne dépend pas de votre code de téléphone.
L’application est protégée par biométrie (Face ID / empreinte).
Après votre disparition, même si un proche accède physiquement à votre téléphone, dès lors que l’ouverture des capsules a été activée, les biométries sont désactivées et il ne pourra pas ouvrir Hylest.
La seule manière d’ouvrir l’application sera d’entrer la question secrète que seul le propriétaire connaissait.
Oui. Hylest propose une offre gratuite avec une capsule simple, appelée Lys.
Avec cette version, vous pouvez créer et modifier votre propre capsule. Vous pouvez aussi recevoir autant de capsules que vous le souhaitez de la part d’autres personnes, sans limite.C’est important : un enfant, un proche ou un héritier peut donc recevoir plusieurs messages, souvenirs ou informations importantes de ses parents ou de sa famille, même sans abonnement payant.Les abonnements payants débutent ensuite à 0,99 €/mois. Il s’agit d’abonnements à durée déterminée, et non d’abonnements à vie.
Oui, Hylest fonctionne partout où les réglementations le permettent.
