2. Scope and documents

These Terms govern Sledge accounts, optional account saving and subscription access. Availability on iPhone depends on Apple offering Sledge in your territory. Android store activation is separate.

The End-User Licence Agreement governs installation and use of the app. The Privacy Policy explains data processing. Receiving that notice is not contractual acceptance or consent. Optional account saving, Health and Agent consent are requested separately. Contractual acceptance never authorises account-save uploads.

Section 8 explains what to know about health and safety before you train with Sledge.

Optional account saving restores your last successfully saved eligible log after sign-in. Unsaved changes and excluded Health-derived records remain on the phone and may be lost on deletion or replacement. Account saving needs its own explicit consent; there is no general database-file import, web checkout or subscription Family Sharing. These Terms grant no right to a function that is not offered.

Builds with Expo over-the-air updates can download compatible interface, JavaScript and asset changes and apply them on a later app launch. Native changes still require a store update. The Privacy Policy explains update delivery.

Data & privacy offers Get a copy of my data, a limited JSON copy of your account-owned local records, without Pro. It excludes imported Health data and is not a backup, import or restore feature. The Privacy Policy explains its scope and your choice of destination. Report an issue sends one report you preview, as Section 6 describes.

3. Account and contract formation

Sign-in is required. A Sledge account contract is formed after the Terms and Privacy notice are shown and you:

  1. confirm that you are at least 18 years old;
  2. accept the current Terms;
  3. acknowledge receiving the Privacy and report notice;
  4. verify Apple sign-in on iOS, Google sign-in on Android or an email address with a one-time code, or use the assigned isolated store-review credential; and
  5. create or access the account.

Sledge records the adult confirmation and Terms acceptance separately from Privacy-notice acknowledgement, including the versions and times. Material changes may require renewed acceptance before continued use. A subscription purchase is a separate store confirmation described below.

4. Authentication and account

Ordinary accounts use Sign in with Apple on iOS, Google on Android or email one-time codes. You must control the chosen identity and keep codes, device access and sessions secure. Do not share a code or sell, transfer or lend the account. Tell us promptly if you believe the account is being used without permission.

One isolated synthetic account supplied only to Apple and Google for store review uses a separate reusable, account-scoped review credential. It exists so store reviewers can inspect the submitted app without access to a company mailbox. The credential cannot authenticate another account and is not available for public registration.

Linking Apple, Google or email requires proof of control of the existing account and the added method. Matching email addresses do not merge accounts. A purchase belongs to its purchasing Sledge account and is not automatically transferred when you switch accounts or restore on the same Apple device.

One Sledge account owns this installation's local log. Confirm ownership when attaching an existing log. Sign-out preserves it; another account requires explicit clearing first. Sign-in can restore the last successfully saved eligible log if account saving was enabled. Purchase restoration manages store access; it does not restore workouts.

Your display name may be a pseudonym. It must not impersonate another person, contain another person's contact details, unlawfully expose personal data, promote hatred or violence, threaten, harass, defraud, advertise, contain malicious links, or otherwise violate law or another person's rights. Automated screening does not make every accepted name lawful.

5. Subscription access

Sledge Pro

Weekly, monthly and annual subscriptions provide the same Pro access. Eligible subscribers may receive a seven-day free trial on each plan where Apple offers it in their country or region.

The annual plan is selected initially. The applicable store's current product information and purchase confirmation determine the price, currency, billing period and trial eligibility shown before you confirm. Introductory eligibility applies across the subscription group; a trial is not promised to every purchaser. After an eligible trial, the selected paid plan renews automatically unless cancelled. Apple on iOS or Google Play on Android charges the store account and handles renewal, plan changes, taxes and refunds under the applicable store terms. Google Play's displayed trial eligibility governs Android purchases; a seven-day Apple offer is not a promise of a Google Play trial.

Use Account > Manage App Store subscription or Manage Google Play subscription to change or cancel through the store where you purchased. Cancel before the renewal shown by that store; for an Apple free trial, Apple advises cancellation at least 24 hours before it ends. Deleting Sledge or its account does not cancel billing. Mandatory withdrawal, conformity and refund rights remain unaffected; follow the information the store presents for the purchase or contact us about Sledge.

Using Sledge requires an active Sledge Pro trial, subscription or complimentary grant. Complimentary access has no store checkout or renewal. Without access, the subscription screen offers Restore purchases, Account, where you can sign out or delete your account, and links to the End-User Licence Agreement (labelled Terms of Use) and the Privacy Policy. Restore purchases is also in Account. Sign in to the Sledge account that purchased first. Do not buy again to resolve a pending purchase or delayed verification.

Access is verified for that account through Superwall. Following successful verification, offline access lasts at most seven days and ends earlier at the known subscription or session expiry. Grace access without a verified future expiry requires an online check. Network failure may delay verification and is shown separately from a confirmed lack of access.

Optional account saving

Account saving serves your own continuity between phones. The Privacy Policy specifies eligible records, photos, exclusions, separate consent, security, retention and rights. Saving works while the app is open and needs a connection. An offline or failed change remains unsaved until the server accepts it. Sledge displays save status and time; two different logs do not merge automatically. Choose explicitly between this phone's log and the saved log when they conflict. Using the saved log can discard unsaved local work after your confirmation. A failed restoration preserves the earlier local log.

The current limits are 32 MiB per snapshot, 5 MiB per prepared photo and 128 MiB of photos per account. Service, network, capacity or key failures can prevent saving or restoration. There is no version history or guarantee that unsaved changes or data lost with the host can be recovered. Mandatory conformity, consumer remedies and liability protections in these Terms remain unaffected. Turn off account saving to stop this phone's uploads immediately and request account-wide erasure of the live save and photos. Offline withdrawal stays pending until confirmed. Clearing the phone or uninstalling alone does not erase the account save. Account deletion removes it under the Privacy Policy's restricted archive retention and recovery rules.

6. Optional AI Agent

When available, Agent requires verified Sledge Pro access, a signed-in account and separate Agent consent. Agent supports iOS and Android where account access is available. AI meal-photo estimates support iOS and Android when enabled and follow the separate food-photo consent described in the Privacy Policy.

Everywhere, Agree and start chatting consents to OpenAI processing of your messages and a bounded recent eligible conversation, including health details you enter, together with your Sledge goals, workouts, food and confirmed body weight and, when you have connected Apple Health or Health Connect under its own consent, your steps, sleep, resting heart rate, Health workouts and Health weigh-ins. There is no partial mode; to stop sharing, turn off Agent. Opening Agent or typing a message gives no permission. An acceptance given before 11 October 2026 did not cover Health data, so Agent asks again. Your message, a bounded recent eligible conversation and summaries of those records pass transiently through Sledge's relay to OpenAI. When an answer needs older records than that summary holds, such as an earlier workout, an exercise history or a longer trend, Agent asks your phone for them and the phone sends only the records asked for, within the same reply. Health data is read for that reply; ordinary Agent processing does not retain it on Sledge's servers. Separately permitted improvement sharing and issue reports are described below. Sledge does not automatically attach your account identifier, account email address or authorization token to model input. Text or photos you choose to send can still identify you or another person; these requests are not treated as anonymous. Without separate improvement-sharing permission, the account service processes only consent, access and usage metadata for an ordinary Agent request. If you allow Help improve Sledge, future meal photos and estimates/corrections and new ordered Agent prompts/replies with relevant context already used in those requests can be saved for restricted human review, as described in Privacy Policy Section 6. Earlier text-only grants remain narrow until a new choice. A deliberate Report an issue submission sends the contextual snapshot you preview and optional comment for encrypted investigation and replies under Privacy Policy Section 8. The snapshot can include the current conversation or a bounded section, request context or a meal photo and estimate; it does not attach the database. Sending one report does not enable ongoing sharing or analytics. The relay does not persist message content.

Conversation and proposal records are stored in the local app database. Eligible conversations and proposals can be included in separately consented account saving; Health-derived content and content of unknown provenance are excluded. Clearing eligible local chat removes it from the next accepted account save. This own-user continuity purpose is separate from Agent processing and Help improve Sledge review. These local records are excluded from automatic backup and device transfer on iOS and Android; see Privacy Policy Section 5. You can stop a reply, clear the local chat or withdraw Agent consent. Stopping or local deletion cannot retract a request already processed by OpenAI. OpenAI API data is not used for model training by default. We request store:false; default abuse-monitoring logs may retain content for up to 30 days, subject to exceptions. This is not a promise of zero retention or exclusively EU processing. See OpenAI API data controls.

Agent is an AI system and may be wrong. It provides general fitness information, not diagnosis, treatment or medical advice. A change you explicitly ask Agent for applies at once with Undo. Agent suggestions and every deletion wait for your tap; Sledge checks current records before committing a change. Applied changes remain in your log after chat deletion. Availability and usage limits may prevent a reply without affecting your existing local records.

Optional processing uses consent under Article 6(1)(a) GDPR and, for health-related information, explicit consent under Article 9(2)(a). You may withdraw prospectively without losing local logging, existing history or account controls. Contact the controller above for access or erasure requests; local deletion does not guarantee immediate erasure of provider-held security records.

7. Account deletion and ending the service

You may stop using Sledge at any time. In-app deletion (Account > Delete account) removes the Sledge account, authentication records, account-save snapshot and saved/staged photos, and this phone's local records, unless another Sledge account owns them. A different account's local records are preserved. Other devices' records remain under your control. Apple Health and Health Connect records need separate management.

The app persists the deletion request and resumes interrupted work. It clears local records only after server deletion is confirmed. A minimal, content-free server receipt supports retry for 30 days after deletion, including after a lost response. A failed request or expired session does not authorize local erasure; sign-in or a retry may be needed. Apple sign-in token revocation must finish before server deletion is confirmed. Without the app, use the web deletion route.

Apple or Google Play subscription cancellation is separate and billing continues until cancelled. Superwall erasure is handled by Burlis through the provider procedure in the Privacy Policy, without a second request from you. Until completion is confirmed, a private handling record retains only the customer UUID and request time. A Sledge deletion receipt does not confirm Superwall erasure.

We may terminate the service for a serious or repeated breach, a security threat, legal necessity or permanent discontinuation. Mandatory notice and consumer rights remain unaffected. Termination does not itself cancel a store subscription.

8. Health, safety and fitness information

What Sledge is. Sledge is a general fitness app for healthy adults. It helps you plan and log strength training, set step and body-weight goals and log what you eat. It is not a medical device and does not diagnose, treat, cure or prevent any disease or injury. Sledge provides general fitness and nutrition information, including AI-generated suggestions. These are not medical advice, medical nutrition therapy or an assessment of whether training or a diet is suitable for your health. They do not replace advice from a qualified professional. Totals, progress and estimates can be incomplete or wrong; check entries before relying on them. Do not use Sledge in an emergency; call 112 or your local emergency number.

Talk to a doctor first if it applies to you. We recommend that you speak to a doctor before you start or significantly change training or nutrition if you are pregnant or have recently given birth; have a heart, circulatory, respiratory, metabolic or musculoskeletal condition, high blood pressure or diabetes; have had a recent injury or surgery; take medication that affects heart rate, blood pressure or balance; have or have had an eating disorder; or are new to strength training and unsure whether it suits you.

Training involves risk. Strength training carries a risk of injury. You decide what, how much and how heavily you lift. Injuries can include muscle, joint and back injuries and, rarely, serious harm. Use a weight you can control with good technique and warm up first. Before you train, check your surroundings and equipment: collars, benches and racks should be in good condition and set up correctly, and the space around you should be clear. Use a spotter or correctly positioned safety arms for lifts where a failed repetition could trap you. Stop immediately and seek medical help if you feel chest pain, dizziness, faintness, unusual shortness of breath or sharp or unusual pain.

Plans and progression are suggestions. Training plans, starting weights and progression suggestions are general suggestions generated from the information you enter. No one at Sledge supervises your training or knows your health or technique. Adjust or skip any suggestion that does not feel right for you.

Agent is an AI system, not a person. Agent replies are generated automatically by an AI model and can be wrong, incomplete or unsuitable for you. A change you explicitly ask Agent to make is applied at once and can be undone for 7 days; a change Agent suggests, and every deletion, waits until you select Apply or Delete. Check what Agent changes. Do not use Agent for medical questions, injuries or emergencies.

Nutrition values are estimates. Meal-photo estimates are generated by AI. Calorie and nutrient values from meal photos, food search, barcodes or calculations are estimates and can differ substantially from the real values. A photo estimate cannot detect allergens, hidden ingredients or how a meal was prepared. Do not rely on Sledge for a medically required diet, for managing an allergy or intolerance, or for insulin dosing.

Goals are general targets. Step, body-weight and calorie goals are based on your inputs, not on an assessment of your health. Aim for gradual change. If you want to lose weight quickly, have a medical condition or have a history of disordered eating, speak to a doctor or registered dietitian first.

This information does not limit our liability; Section 11 sets out the liability rules.

Health integration is optional and requires separate explicit consent followed by the operating-system permission. Health consent is separate from acceptance of these Terms. You remain responsible for what you choose to record and for reviewing anything Sledge writes to Apple Health or Health Connect.

9. Availability, maintenance and changes

We use reasonable care to operate Sledge, but do not promise uninterrupted or error-free availability. Maintenance, security work, provider outages and legal requirements may temporarily restrict it.

We may make proportionate changes for security, compatibility, legal or app-store requirements, or abuse prevention. Changes do not add costs. We explain changes clearly.

If a change has more than a minor negative effect on your access to or use of Sledge, we will notify you reasonably in advance on a durable medium, such as email. The notice will explain the change, its timing and your right to end the affected contract free of charge within 30 days of receiving that notice or the change taking effect, whichever is later. This termination right does not apply if we keep the unchanged service available to you at no extra cost. Contact us using Section 1 to exercise this right; account deletion is not required. Statutory refund rights and other mandatory rights concerning digital products and updates remain unaffected.

10. Intellectual property and acceptable use

Sledge software, design, name and original content are protected by law. The EULA grants the app licence. Except where mandatory law or an open-source licence allows it, you must not bypass security or access controls, probe the service without permission, scrape account data, automate unsupported requests, introduce malware, disrupt the service, obtain another user's credentials, or use Sledge unlawfully.

Third-party and open-source components remain subject to their own licences. Notices and applicable texts are available in the app. The licences page explains how to request a copy.

11. Warranty and liability

German statutory warranty and consumer rights apply. Your statutory rights as a consumer, in particular your rights regarding defects in and updates to digital products (Sections 327 et seq. German Civil Code), remain unaffected; the following rules concern only liability for damages.

Nothing in these Terms limits liability for intent, gross negligence, injury to life, body or health, fraudulent concealment, an expressly assumed guarantee, liability under the German Product Liability Act (Produkthaftungsgesetz), or another liability that cannot legally be limited.

For slight negligence, Burlis is liable for breach of an essential contractual duty only for the foreseeable damage typical for the contract. An essential duty is one whose performance makes the contract possible and on which the user may ordinarily rely. Otherwise, we are not liable for slight negligence. These limits also apply to employees and agents.

If your own fault contributed to a loss, for example by ignoring pain, warnings or safe lifting practice, it is taken into account under the statutory rules (Section 254 German Civil Code).

You remain responsible for protecting your device. This does not remove liability where Burlis caused a loss under the rules above.

12. Privacy and communications

Personal-data processing is governed by the Privacy Policy. Acceptance of these Terms does not grant Health consent.

Contractual notices may be provided in the app, on the Sledge website or by email to a linked account address where appropriate. This does not replace a form required by law.

13. Consumer dispute resolution

Burlis Management GmbH is neither obliged nor willing to participate in dispute-resolution proceedings before a consumer arbitration board.

If a dispute under a consumer contract could not be settled directly, Burlis will provide the information required in the individual case by Section 37 of the German Consumer Dispute Resolution Act. This statement does not restrict access to courts, authorities or consumer organisations.

14. Governing law, language and final terms

German law applies, excluding the UN Convention on Contracts for the International Sale of Goods. If you are a consumer, this choice of law does not deprive you of the protection of the mandatory provisions of the law of the country where you have your habitual residence (Article 6(2) Rome I Regulation). No exclusive place of jurisdiction is imposed on a consumer.

These Terms are concluded in English; no other contract language is offered. This does not limit mandatory consumer protection.

If a provision is invalid, the statutory rule applies and the remainder stays effective where legally possible. Failure to enforce a right once is not a waiver. Questions may be sent to the provider contact in Section 1.
