Effective Date: May 15, 2026 Last Updated: May 15, 2026
By downloading, installing, or using the Witness mobile application (“App,” “Witness,” or “the Service”) you agree to be bound by these Terms of Service (“Terms”). If you do not agree, do not use the App.
These Terms constitute a legally binding agreement between you (“User,” “you,” or “your”) and Cankat Saraç (“we,” “us,” or “our”), the developer and operator of Witness.
Read this section before using Witness.
Witness simulates a short conversation with a generated representation of yourself at age 80. The simulation is produced by:
The aged portrait, the synthesized voice, and the replies are not a real prediction of your future, a real memory, or any kind of medical, psychological, financial, or life-planning advice. The replies are statistically generated text. They may be moving, surprising, or uncomfortable. They may also be wrong, awkward, or out of touch with your actual circumstances.
If you are experiencing mental-health difficulties, grief, depression, anxiety, suicidal ideation, or any acute distress, please seek help from a qualified clinician or crisis service in your country. Witness is not a therapeutic tool and does not substitute for professional support. In a mental-health emergency, contact a crisis line in your country (e.g., 988 Suicide & Crisis Lifeline in the US, Samaritans at 116 123 in the UK).
By continuing to use Witness you acknowledge that you understand the nature of the simulation, that the older self speaking to you is not you, and that nothing in the App constitutes medical, mental-health, legal, financial, or professional advice.
Witness lets you:
Witness does not run a social network. The conversation is not shared with anyone else.
You must be at least 13 years old to use Witness. Users in the European Economic Area must be at least 16 years old, or must have verifiable parental or guardian consent.
You represent that you have the legal capacity to enter into these Terms in your jurisdiction.
You represent that the selfie and the voice sample you provide are of you, the actual user of the device, and that you have the legal capacity to consent to biometric processing as described in the Privacy Policy. You may not submit the face or voice of any other person. Submitting the imagery or voice of another individual without their explicit, informed consent is a material breach of these Terms and may also violate biometric-privacy statutes (BIPA, CUBI, etc.) and right-of-publicity laws in your jurisdiction. You agree to indemnify us against any claim arising from your breach of this clause.
You retain ownership of the content you generate inside Witness — the aged portrait, the conversation text, and the synthesized audio replies.
To operate the App for you, you grant us a limited, non-exclusive, royalty-free, worldwide license to transmit your selfie to the AI image service, transmit your conversation text to the AI text service, and transmit reply text to the text-to-speech service, solely for the purpose of generating the aged portrait, the voiced replies, and the conversation. This license terminates as soon as the relevant inference call completes.
We do not direct any of our service providers to use your selfie, voice sample, or conversation text to train their models. Where the provider’s own terms confirm an “API inputs not used for training” position (e.g., OpenAI’s published API data-use policy), that position governs. We will not knowingly contract with a provider that requires training on user inputs as a condition of service.
Witness Pro unlocks features that may include extended capacity, additional capture or reset options, contextual mode (bio and social context), and access to new capture formats as they ship. Specific feature lists are presented in the App at the time of purchase.
Witness Pro is offered as one or more of the following plans (subject to App-shown availability):
Prices are displayed in your local currency at purchase.
Recurring subscriptions are billed through Apple App Store or Google Play. Subscriptions automatically renew at the end of each billing period unless cancelled at least 24 hours before the end of the current period.
If a free trial is offered, Apple or Google will capture your payment method at trial start and will charge you at the end of the trial unless you cancel.
Cancellation is handled by the platform store:
The App cannot cancel subscriptions on your behalf, consistent with Apple App Store Review Guideline 3.1.1 and Google Play policy.
Refunds are handled by Apple or Google according to their respective policies. We do not independently process refunds.
A Restore Purchases option is available on the paywall and in account settings.
If you are a consumer in the European Union or United Kingdom, the 14-day right of withdrawal for digital content is presented and captured by the platform store at checkout in accordance with the EU Consumer Rights Directive (Directive 2011/83/EU, as amended) and the UK Consumer Contracts (Information, Cancellation and Additional Charges) Regulations 2013. The platform store is the seller of record for the purposes of the withdrawal right. Nothing in these Terms limits your statutory consumer rights.
All elements of Witness — including the code, design, prompts, voice-selection logic, copy, and brand — are the intellectual property of Cankat Saraç, protected by copyright, trademark, and other applicable IP law.
We grant you a limited, non-exclusive, non-transferable, revocable license to use the App on your personal device for personal, non-commercial purposes.

You agree not to use Witness to:
We may suspend or terminate access at any time for material breach of these rules.
The App is provided “as is” and “as available” without warranties of any kind, express or implied, including merchantability, fitness for a particular purpose, accuracy, or non-infringement.
We do not warrant that the aged portrait is accurate, flattering, or representative of any real future state. We do not warrant that the older self’s replies are accurate, helpful, comforting, or appropriate to your situation.
Nothing in Witness constitutes medical, mental-health, legal, financial, or other professional advice. See Section 2.
TO THE MAXIMUM EXTENT PERMITTED BY APPLICABLE LAW, IN NO EVENT SHALL CANKAT SARAÇ, HIS AFFILIATES, LICENSORS, OR SERVICE PROVIDERS BE LIABLE FOR ANY:
WHETHER BASED ON WARRANTY, CONTRACT, TORT (INCLUDING NEGLIGENCE), OR ANY OTHER LEGAL THEORY, EVEN IF WE HAVE BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES.
OUR TOTAL LIABILITY FOR ANY CLAIM ARISING OUT OF OR RELATING TO THE APP SHALL NOT EXCEED THE AMOUNT YOU PAID US IN THE TWELVE (12) MONTHS PRECEDING THE CLAIM, OR USD $10.00, WHICHEVER IS GREATER.
Some jurisdictions do not allow these exclusions or limitations; in such jurisdictions our liability is limited to the maximum extent permitted by law.
Nothing in these Terms affects your statutory rights under mandatory EU or UK consumer-protection law.
You agree to indemnify, defend, and hold harmless Cankat Saraç, his affiliates, and their respective directors, officers, employees, and agents from any claims, liabilities, damages, losses, and expenses (including reasonable legal fees) arising out of or in connection with:
Witness integrates with fal.ai, ElevenLabs, the Rork Toolkit (relaying to OpenAI’s GPT-4o), RevenueCat, and the Apple App Store / Google Play Store. Each is governed by its own terms. We are not responsible for those services.
We may modify, suspend, or discontinue the App at any time, with or without notice.
We may revise these Terms. Material changes are communicated via in-app notice on the next launch. Continued use after the effective date of revised Terms is acceptance.
Uninstall the App. This deletes all locally cached content immediately.
We may terminate or suspend your access for material breach (in particular, breach of the identity authenticity clause in Section 4.3). No refund of unused subscription time is owed beyond what is required by applicable law and platform store policies.
These Terms are governed by the laws of the Republic of Türkiye, without regard to its conflict-of-laws principles.
You agree to contact us at cankatsarac@gmail.com and attempt informal resolution for at least 30 days before bringing any formal claim.
For users outside the EU and UK, disputes not resolved informally shall be submitted to binding individual arbitration under the Rules of the Istanbul Arbitration Centre (ISTAC), seated in Istanbul, Türkiye, conducted in English. You waive any right to participate in class actions or class arbitration. If the class waiver in this clause is held unenforceable in your jurisdiction for a particular dispute, the remainder of this Section 14 remains in effect.
You may bring proceedings in the courts of your country of residence and benefit from mandatory consumer protections. The EU Online Dispute Resolution platform is at https://ec.europa.eu/consumers/odr.
You may bring proceedings in the courts of England and Wales, Scotland, or Northern Ireland as applicable.
These Terms and the Privacy Policy are the entire agreement between us about the App.
Unenforceable provisions are severed; the remainder continues in effect.
Failure to enforce is not waiver.
You may not assign these Terms. We may assign to a successor in connection with merger, acquisition, or sale of assets.
These Terms create no partnership, joint venture, employment, or agency relationship.
If you obtained the App through the Apple App Store, you acknowledge:
