HYREN is a HYROX training app. It builds your plan from your own data — your readiness, your limiters and your race pace — and re-writes it every week as those change. It trains the whole race, not just the workout.

No — and HYREN does not currently read one. It does not connect to Apple Health, Health Connect, or any watch, and it reads no sleep, heart-rate, HRV, blood-oxygen or VO₂max data from your phone. It works entirely from the sessions you log, and readiness calibrates as you train.

Wearable sync is planned. Until it ships, HYREN requests no access to Apple Health and reads nothing from it.

No. HYREN is a training tool, not a medical device. Loads, paces, readiness scores and race projections are training guidance — not a diagnosis, a treatment, or professional advice. Consult a qualified professional before starting any programme, and stop and seek help if you feel pain, dizziness, chest discomfort, shortness of breath, or any unusual symptom.

No. HYROX® is a registered trademark of its owner. HYREN is an independent training app, and is not affiliated with, endorsed by, or sponsored by HYROX.

HYREN is built and operated by Mohamed Sheha as an individual (sole trader), who is also the data controller responsible for your personal data. You can read the whole story on Who we are.

You must be 16 or older to use HYREN. We do not knowingly collect data from anyone under 16.

One engine, four steps. It reads your readiness, your accumulated load and your race context; it decides using deterministic safety and progression rules; it gives you one session that fits today; and it learns from what you completed and how it felt, which updates the state the next decision is made from.

The decision itself is rule-bounded and explainable — see Who we are.

HYREN re-scores every session against your race date and your recent training. Missing a session, logging a hard effort, or a drop in readiness will re-shape the week. The app explains the reason on the session card.

A score HYREN computes from what you record — your sessions, your session RPE, your soreness and energy check-ins, and any pain flags. It is used to shape the day's training.

It is an estimate, and it can be wrong. Readiness and injury-risk signals help you make a decision; they are not a guarantee that training is safe on any given day.

Yes. HYREN gives guidance, not instructions — you decide what you actually do, and logging what you did is what keeps the next decision honest.

Your readiness score, your training load, your estimated one-rep maxes, your projected race finish and gap to goal, and a five-day recovery projection. All of it is derived from what you log — nothing is read from a device.

Only what you enter or generate inside the app:

• Your training logs — sessions, exercises, sets, reps, loads, paces, reps-in-reserve and form notes.
• Subjective inputs — session RPE, soreness and energy check-ins, and pain flags.
• Derived values — readiness, training load, estimated one-rep maxes and projected finish.

This is treated as sensitive (special-category) data and given extra protection.

No. HYREN does not connect to Apple Health, Health Connect, or any wearable, and reads no sleep, heart-rate, HRV, blood-oxygen or VO₂max data from your phone or watch.

So it can train around them. You give HYREN this only by choosing to record it, under your explicit consent, and none of it is required to use the app. It is used only to adapt your training to your recovery. It is never used for advertising or marketing, and never shared with third parties for their own purposes.

Yes. You can edit or clear these entries at any time, and export or delete your account from Settings. Health and training data is removed immediately.

Stop, and seek help. Exercise carries inherent risk and you take part voluntarily and at your own risk. If you describe an acute symptom to the AI Coach, HYREN stops giving training advice and tells you to see a professional.

When you send a coach message, the text of that message is sent to Anthropic, our AI provider, together with a summary of your current training numbers — readiness, recent sessions, goal — solely to generate a reply. It is not used to train their models.

No. Each message is sent, answered, and discarded. The coach has no memory of previous messages, and there is no transcript in your account — so there is nothing to export and nothing to delete.

Please don't. The coach gives training guidance, not medical advice. If you describe an acute symptom, it will stop advising on training and tell you to see a qualified professional.

HYREN answers from its own built-in logic instead, and nothing leaves our backend.

No. The training decision is deterministic — rule-bounded, with visible constraints and safety gates, and traceable back to the readiness, load and progression rules that produced it. AI helps build and narrate the experience; it does not invent the training decision.

No, and we never will. We don't run ads. We use no third-party analytics, advertising SDKs or trackers. We don't collect your precise location, your contacts, your photos, or advertising identifiers.

In the app: You → Privacy & legal → Export my data. You get everything as a structured, machine-readable JSON file. No email required, and it is always free.

Same screen: You → Privacy & legal → Delete my account. Your account, sign-in, health and training data is removed immediately. Deletion is irreversible.

One narrow exception: if an Apple subscription is still active we retain the billing-contact email and the minimum subscription facts needed to send legally required notices, until that subscription ends.

A small number of providers, who process it only on our instructions:

• Convex (USA) — stores your account and training data and runs the backend.
• Resend (USA) — delivers verification, recovery, purchase and renewal emails.
• Anthropic (USA) — generates AI Coach replies.
• Expo (USA) — delivers the notifications you opt into, and serves corrected app code between App Store releases. That update check runs every time the app opens and sends your platform, the app's runtime version and your IP address — no account identifier, and none of your training data.
• Apple — sells and bills HYREN Pro, and carries push notifications to your device. Apple handles payments as an independent controller under its own privacy policy, not on our instructions.

Some providers, including Convex, are based in the United States. Where your data is transferred outside the UK or EEA, we rely on appropriate safeguards such as the provider's Standard Contractual Clauses or an equivalent transfer mechanism.

As long as your account exists. Data you delete in the app is removed from our live systems immediately and purged from encrypted backups within 30 days. If your account is inactive for 24 months we may delete it, after first trying to contact you.

It is encrypted in transit (TLS) and stored with our cloud provider's encryption at rest. Sign-in tokens are held in your device's secure keychain, and access is keyed to your authenticated account — one user cannot read another's data.

HYREN is free to use, and stays free. These are never behind the paywall, at any price: today's session, the live runner and per-set logging, your readiness score and the recovery body, your records, your notifications, exporting your data, and deleting your account.

HYREN Pro unlocks unlimited training history and trends, your projected finish and gap to goal, the full session Library including the race simulations, unlimited saved custom sessions, the five-day recovery projection, race-week taper and fuelling, and a higher AI Coach allowance.

US$12.99 per month or US$89.99 per year. Outside the United States, Apple sets the price for your storefront in your local currency. The exact price, the billing period and the date of the first charge are shown on the purchase screen before you buy anything.

Two separate things, and they are not the same:

• Apple's trial — new subscribers get 14 days free on either plan. Apple allows one free trial per person per subscription group, so if you have used it on one plan you will not get a second on the other.
• Our grant — every new HYREN account gets seven days of Pro on us when it is created. That is a gift, not a purchase: no card, no Apple prompt, nothing to cancel. It simply ends after seven days.

Apple — Apple is the seller and merchant of record, which for users in the EU, the UK, Switzerland, Norway and Iceland is Apple Distribution International Ltd. Payment is charged to your Apple Account. We never see your card details.

On your device: Settings → your name → Subscriptions → HYREN, or Manage subscription in HYREN's Settings, which opens the same screen. Cancel at least 24 hours before the period ends, or Apple will charge for the next one.

Cancelling takes effect at the end of the period you have already paid for — you keep Pro until then.

No. Apple keeps billing until you cancel with Apple. You can cancel first, or delete anyway — but the subscription is Apple's to stop, not ours.

Refunds for App Store purchases are handled by Apple, and Apple alone decides them. We cannot issue a refund and we cannot overturn one. Request one at reportaproblem.apple.com, or in the App Store under your account.

What we can do is give you service: if something on our side went wrong, tell us at billing@hyrenapp.com and we may extend or comp your access. Nothing here takes away a refund or cancellation right the law gives you.

You have it, and it runs against Apple, because Apple is the seller — so you exercise it through Apple, at reportaproblem.apple.com, within 14 days of your receipt and without giving a reason.

Before you buy, you separately confirm that you want Pro supplied immediately and that you understand you lose the withdrawal right once it has been fully supplied. That tick is never pre-ticked and is never bundled into accepting the Terms. If you did not give it, the right is unaffected.

We email you at least 7 and no more than 30 days before it takes effect, with the new price and how to cancel. Where your storefront requires consent and you do not give it, the subscription will not renew at the new price. On an annual plan we also email roughly 30 days before each renewal with the date, amount and cancellation instructions.

Nothing of yours is deleted. The Pro features lock and the free tier carries on exactly as before. Every session you logged, every record, every custom session stays in your account — and comes back the moment you resubscribe.

An email address and a password, which we store only as a secure hash. If you sign in with an Apple account that supplies no usable address, you will be asked to verify a billing-contact email before you can purchase.

Only the ones you opt into — training reminders, readiness and taper alerts. If you turn them on we store a push token so we can deliver them. No health data goes into a notification.

Tell us immediately at support@hyrenapp.com. You are responsible for keeping your login details secure and for activity under your account, so change your password as well.

Email support@hyrenapp.com — we aim to reply within two working days. Include your account email, your device and iOS version, and what you expected to happen.
