Section 5 — Orders and Payments

All product purchases are subject to acceptance and availability. Product prices are displayed in Euros (€) and are subject to change without prior notice. Prices include applicable taxes unless otherwise stated.

We reserve the right to refuse or cancel any order at our sole discretion, including orders that appear fraudulent, that are placed by resellers without authorization, or that contain errors in pricing or product information.

Payment must be made in full at the time of purchase through our approved payment processors. You represent that you are authorized to use the payment method provided.

Section 6 — Shipping and Delivery

Product prices include VAT and worldwide shipping. Shipping is provided on an INCOTERM DAP (Delivered at Place) basis: customs duties, import tariffs, and other import charges applicable in the destination country are the sole responsibility of the buyer.

Estimated delivery times are provided for informational purposes only and are not guaranteed. We are not liable for delays caused by customs, carriers, or circumstances beyond our control.

Risk of loss and title for products pass to you upon delivery to the carrier.

Section 7 — Returns and Refunds

Right of withdrawal. You may withdraw from your purchase within 14 days of receiving your order, without giving any reason. Just tell us before the period ends — a clear statement by email is enough. To start a return, please contact us.

You may examine the product. You are entitled to unpack, handle and power on the device to establish its nature, characteristics and functioning, exactly as you could in a shop. Doing so does not affect your right to withdraw. We may reduce your refund only if the product's value has been diminished by handling that goes beyond this. Please return the device complete, with the accessories included in the box.

Return shipping. You bear the direct cost of returning the product. This does not apply if the product is faulty or was sent in error — in that case we cover the return.

Refund. We will refund all payments received from you, including the standard delivery cost, using the same means of payment you used, within 14 days of being informed of your decision to withdraw. We may withhold the refund until we have received the product back or you have supplied proof of having sent it, whichever is earlier.

This policy applies to all customers worldwide. Your statutory rights — including the two-year legal guarantee of conformity described in Section 18 — are not affected.

Section 8 — Community Earthquake Reports

8.1 Nature of Community Reports

Community earthquake reports are user-generated content submitted by individual users based on their subjective perception of ground shaking. These reports are:

• NOT verified seismic measurements from calibrated instruments
• NOT official earthquake data from any governmental or scientific authority
• NOT validated, confirmed, or endorsed by seismological institutions, emergency management agencies, or APPFLOWS TEKNOLOJİ ANONİM ŞİRKETİ

Community reports are aggregated algorithmically to identify potential seismic events. The resulting "community earthquakes" are statistical aggregations of user-submitted data, not confirmed seismological events.

8.2 No Guarantee of Accuracy

We make no representation or warranty regarding the accuracy, completeness, timeliness, or reliability of any community earthquake report, community earthquake event, or notification generated from community data. Reports and derived data may be:

• Inaccurate due to user error, misperception, or subjective judgment
• Delayed due to network conditions, server processing, or device connectivity
• Affected by non-seismic vibrations (e.g., heavy traffic, construction, industrial activity, or meteorological phenomena)
• Subject to false or malicious submissions, despite our anti-abuse measures (CAPTCHA, rate limiting, reputation scoring)
• Incorrectly clustered, geolocated, or assigned intensity levels by our automated algorithms

8.3 Not a Substitute for Official Systems

Community reports and alerts generated by the GeoShake platform are supplementary information only and do NOT replace:

• Official national and regional earthquake monitoring systems (e.g., AFAD, USGS, EMSC, JMA)
• Government-issued earthquake early warning systems
• Emergency broadcast systems, civil defense alerts, or public warning sirens
• Professional seismological analysis, damage assessment, or safety inspections
• Building safety codes, evacuation plans, or emergency preparedness protocols

Users must always follow official guidance from local and national emergency management authorities for all life-safety, evacuation, and emergency response decisions.

8.4 Limitation of Liability for Community Reports and Alerts

TO THE MAXIMUM EXTENT PERMITTED BY APPLICABLE LAW, APPFLOWS TECHNOLOGY, ITS OFFICERS, DIRECTORS, EMPLOYEES, AGENTS, AND AFFILIATES SHALL NOT BE LIABLE FOR ANY DIRECT, INDIRECT, INCIDENTAL, SPECIAL, CONSEQUENTIAL, EXEMPLARY, OR PUNITIVE DAMAGES, INCLUDING BUT NOT LIMITED TO DAMAGES FOR PERSONAL INJURY, DEATH, PROPERTY DAMAGE, LOSS OF PROFITS, LOSS OF DATA, EMOTIONAL DISTRESS, OR ANY OTHER LOSSES, ARISING FROM OR IN CONNECTION WITH:

• Any reliance on community earthquake reports, community earthquake events, notifications, or alerts generated through the Services
• Failure to detect, report, or alert users of an actual seismic event
• Delayed, incomplete, or inaccurate alerts or notifications
• False positive alerts (alerts generated when no actual earthquake occurred)
• False negative outcomes (failure to generate an alert when an earthquake did occur)
• Any decisions, actions, or omissions taken by users based on data, reports, or alerts from the Services
• Incorrect seismic intensity calculations, geographic clustering, or magnitude estimates produced by our algorithms
• Actions or reports submitted by other users of the Services

8.5 User Responsibility When Submitting Reports

By submitting a community earthquake report through the Services, you represent and warrant that:

• You have genuinely felt ground shaking or seismic activity at the time of reporting
• The intensity level you selected reflects your honest and good-faith perception of the shaking
• You understand that your report will be aggregated with reports from other users and may contribute to the generation of community earthquake alerts sent to other users
• You consent to sharing your approximate geographic location with the report for the purpose of seismic event clustering and geographic analysis
• You accept that your report becomes part of a community dataset and may be used, in anonymized and aggregated form, for scientific research, public safety analysis, and service improvement

8.6 Abuse and Enforcement

We reserve the right, at our sole discretion, to:

• Remove, disregard, or quarantine reports that appear to be false, automated, malicious, or otherwise in violation of these Terms
• Suspend or permanently terminate accounts that repeatedly submit false reports or abuse the community reporting system
• Adjust reputation scores to reflect the accuracy and reliability of a user's reporting history
• Implement, modify, or strengthen rate limits, CAPTCHA requirements, geographic restrictions, or other anti-abuse measures at any time without prior notice
• Cooperate with law enforcement authorities if false reporting constitutes a criminal offense under applicable law

Section 9 — Seismic Data Disclaimer

In addition to community earthquake reports, the GeoShake platform processes seismic sensor data from hardware devices (e.g., GeoShake T1, DIY nodes). The following disclaimers apply to all seismic data provided through the Services:

• Hardware sensor data is experimental and may contain errors, noise, or artifacts due to sensor calibration, device placement, environmental conditions, or firmware limitations
• Richter magnitude estimates, Modified Mercalli Intensity (MMI) calculations, and damage assessments derived from sensor data are algorithmic approximations and are not official seismological measurements
• GeoShake hardware devices are consumer-grade instruments and are not calibrated to the standards of professional seismological equipment maintained by national geological surveys
• Sensor data quality may be affected by temperature, humidity, building vibrations, traffic, and other environmental factors beyond our control
• Historical seismic data may be corrected, modified, recalibrated, or removed without prior notice as part of ongoing data quality improvements
• Real-time data streams may experience latency, interruptions, or data loss due to network conditions, server load, or device connectivity issues

Section 10 — Disclaimer of Warranties

EXCEPT FOR THE GEOSHAKE LIMITED WARRANTY IN SECTION 18, THE SERVICES ARE PROVIDED "AS IS" AND "AS AVAILABLE" WITHOUT WARRANTIES OF ANY KIND, WHETHER EXPRESS, IMPLIED, OR STATUTORY. TO THE FULLEST EXTENT PERMITTED BY LAW, WE DISCLAIM ALL WARRANTIES, INCLUDING BUT NOT LIMITED TO IMPLIED WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, TITLE, AND NON-INFRINGEMENT.

WITHOUT LIMITING THE FOREGOING, WE DO NOT WARRANT THAT:

• The Services will be uninterrupted, timely, secure, or error-free
• Earthquake alerts or notifications will be delivered promptly, accurately, or at all
• Community earthquake reports reflect actual seismic events
• Seismic data from hardware devices is accurate, complete, or reliable
• The Services will detect all earthquakes in your area
• Intensity, magnitude, or location estimates are correct

SEISMIC DATA, EARTHQUAKE ALERTS, COMMUNITY REPORTS, AND EARLY WARNING NOTIFICATIONS ARE PROVIDED FOR INFORMATIONAL AND EDUCATIONAL PURPOSES ONLY AND SHOULD NOT BE RELIED UPON AS THE SOLE BASIS FOR LIFE-SAFETY, EVACUATION, PROPERTY, OR FINANCIAL DECISIONS. USERS SHOULD ALWAYS FOLLOW OFFICIAL GUIDANCE FROM LOCAL AND NATIONAL EMERGENCY MANAGEMENT AUTHORITIES.

Section 11 — Limitation of Liability

TO THE MAXIMUM EXTENT PERMITTED BY APPLICABLE LAW, IN NO EVENT SHALL APPFLOWS TECHNOLOGY, ITS OFFICERS, DIRECTORS, EMPLOYEES, AGENTS, OR AFFILIATES BE LIABLE FOR ANY INDIRECT, INCIDENTAL, SPECIAL, CONSEQUENTIAL, EXEMPLARY, OR PUNITIVE DAMAGES, INCLUDING BUT NOT LIMITED TO LOSS OF PROFITS, DATA, USE, GOODWILL, OR OTHER INTANGIBLE LOSSES, ARISING OUT OF OR IN CONNECTION WITH YOUR USE OF THE SERVICES.

THIS LIMITATION SPECIFICALLY INCLUDES, WITHOUT LIMITATION, ANY CLAIMS ARISING FROM: INACCURATE OR FALSE COMMUNITY EARTHQUAKE REPORTS; FAILURE TO DELIVER OR DELAYED DELIVERY OF EARTHQUAKE ALERTS OR EARLY WARNING NOTIFICATIONS; FALSE POSITIVE OR FALSE NEGATIVE SEISMIC EVENT DETECTIONS; INCORRECT SEISMIC INTENSITY, MAGNITUDE, OR LOCATION CALCULATIONS; AND ANY RELIANCE ON COMMUNITY-SOURCED DATA FOR LIFE-SAFETY, PROPERTY PROTECTION, EVACUATION, OR FINANCIAL DECISIONS.

OUR TOTAL AGGREGATE LIABILITY FOR ANY CLAIMS ARISING FROM THIS AGREEMENT SHALL NOT EXCEED THE GREATER OF: (A) THE AMOUNT YOU PAID TO US IN THE TWELVE (12) MONTHS PRECEDING THE CLAIM; OR (B) ONE HUNDRED EUROS (€100).

Section 12 — Indemnification

You agree to indemnify, defend, and hold harmless APPFLOWS TEKNOLOJİ ANONİM ŞİRKETİ and its officers, directors, employees, agents, and affiliates from and against any claims, liabilities, damages, losses, costs, or expenses (including reasonable attorneys' fees) arising out of or related to: (a) your use of the Services; (b) your violation of these Terms; (c) your violation of any rights of a third party; (d) your negligence or willful misconduct; (e) community earthquake reports you have submitted; or (f) any claim that your use of the Services caused harm to a third party.

Any disputes arising from or relating to these Terms or the Services shall be subject to the exclusive jurisdiction of the courts located in Antalya, Turkey.

Section 15 — Severability

If any provision of these Terms is held to be invalid, illegal, or unenforceable, such provision shall be modified to the minimum extent necessary to make it valid and enforceable, or if modification is not possible, shall be severed from these Terms. The remaining provisions shall continue in full force and effect.

Section 16 — Termination

We may suspend or terminate your access to the Services at any time, with or without cause and with or without notice. Upon termination, your right to use the Services will immediately cease. Provisions of these Terms that by their nature should survive termination shall survive, including but not limited to intellectual property provisions, disclaimers, limitations of liability, indemnification obligations, and the community earthquake reports and seismic data disclaimers.

Section 17 — Modifications

We reserve the right to modify these Terms at any time. Material changes will be communicated through the Services (in-app notification), on our website, or by email to registered users. Your continued use of the Services following the posting of changes constitutes your acceptance of such changes. We encourage you to review these Terms periodically.

Section 18 — Warranty and Legal Guarantee

GeoShake Limited Warranty. We warrant that the GeoShake T1 will be free from defects in materials and workmanship for one (1) year from the date of delivery. This is a warranty we give voluntarily, and it is in addition to any rights you may have under the law of your own country.

If a defect appears within this period, contact us at info@geoshake.org with your order number and device ID before returning anything. Your station reports its own diagnostic data, so in most cases we can identify the cause remotely. We will tell you whether the fault is covered before you ship the unit — you will never have to pay for return shipping without knowing where you stand.

If the fault is covered by this warranty, we will, at our option, either send you a replacement unit or refund the price you paid, and we will reimburse your return shipping cost. Outbound shipping of a replacement is always at our expense. We may waive the return of the faulty unit at our discretion.

If the fault is not covered, return shipping is at your expense and we will offer you a replacement unit at a reduced price. We do not offer component-level repair.

Not covered: accidental damage, liquid ingress, lightning or power surge, damage in transit after delivery, damage caused by physical modification of the hardware, normal cosmetic wear, and any fault caused by installing the device outside the conditions described in the setup guide.

Custom firmware does not void this warranty. GeoShake T1 firmware is open source and you are free to modify it and flash your own. We do not warrant the behavior of firmware we did not publish, but running it does not affect your hardware warranty.

EU/EEA consumers. If you are a consumer in the European Union or the European Economic Area, you benefit from a legal guarantee of conformity under Directive (EU) 2019/771 for a period of two years from delivery of the product. If the product does not conform to the contract, you may ask us to bring it into conformity — by repair or replacement in the first instance — free of charge.

These rights apply independently of, and are not limited by, the return policy in Section 7 or the GeoShake Limited Warranty above, and your statutory rights under local law remain unaffected. To make a claim under the legal guarantee, please contact us at info@geoshake.org.

Section 19 — Contact
